Single-Lens Optical Path Redesign - 18/06/2026 06:37 EDT

@mahmoudralizadeh

Replacing a dual-lens diffuser stack with a single catalog condenser lens while preserving a 30 mm entrance aperture compression onto a 5 mm detector without sacrificing uniformity is fundamentally a constrained étendue-matching problem. The key difficulty is maintaining angular acceptance while controlling aberrations and preventing edge vignetting within a single refractive element. My approach is structured as follows: (1) identify suitable off-the-shelf PCX or aspheric condenser lenses from Zeiss/BM Optik catalogs with compatible NA and focal length ranges, (2) build a non-sequential ray-tracing model to evaluate spot size, encircled energy, and spectral throughput, (3) optimize lens-to-source and lens-to-detector spacing to balance field coverage and telecentricity constraints, and (4) run tolerance analysis for manufacturability in printed or machined mounts. I have experience developing compact optical and electro-optical systems using numerical ray tracing and CAD-driven mechanical integration workflows, particularly where cost reduction is a primary constraint. Deliverables include a Zemax/OpticStudio file, STEP mechanical model, Python-based verification script, optical performance report, and tolerance analysis documentation, with up to two revision cycles included. The proposed timeline is preliminary and will be refined after reviewing exact geometry constraints and detector acceptance limits. What is the allowable longitudinal envelope between entrance aperture and detector plane, and is there any constraint on spectral bandwidth weighting within the visible range?

Hi there, i can do create Single-Lens Optical Path Redesign according to your requarment. I am professional mechanical engineer and 3D artist with the experience of nine years in 3d designing field. I have great skill of 3d designing, I have good grasp of 3d printing program. I am using Creo 3.0, Catia, Cad-cam, Auto-cad and Solid work for 3d printable modeling. I have read your job description. I understood your project. I am ready for this job. I would like to work with you. My bid budget is negotiate. Please have a look on our 3D work given below:-

@vishal1145

This job requires specialized optical engineering expertise (Zemax ray tracing, lens selection, aberration analysis) that falls outside core software development. While Python is listed, the primary deliverable is optical design work, not software.

The real bottleneck isn’t merely removing one lens — it’s preserving acceptance angle and limiting new spherical/chromatic aberrations so the 30 mm entrance still maps cleanly to 5 mm without vignetting or photon loss. I’ll run a targeted workflow: shortlist candidate off‑the‑shelf Zeiss and B&M Optik singlets (focus on aspheric/plano‑convex condensers), build full ray‑traces in OpticStudio (with a Python backup using Raysect), compute spot diameter and spectral energy throughput (400–700 nm), and export Zemax reports plus screenshots. I’ll then create a 3‑D CAD assembly (STEP + simple 2D drawing) with a ±0.1 mm focus adjustment and mounting tolerances suitable for 3D printing/ basic machining. If needed I’ll specify a thin diffuser or minimal baffle and quantify its impact. Recommended tools: Zemax/OpticStudio (primary), Python+Raysect for reproducible scripts; CAD in SolidWorks or FreeCAD (STEP export). I’ll deliver datasheet/part number justification for the chosen lens and an efficiency comparison vs your current stack. I’ve previously delivered single‑element condenser replacements for handheld light sensors—Zemax model, STEP file and measured throughput—happy to share those files. Quick question: what’s the detector’s acceptance angle or measured angular FOV (and do you have current measured photon throughput vs wavelength?) If you confirm, I’ll begin the candidate shortlist and ray‑trace plan.

With a background in optical engineering and experience in designing light paths, I understand the challenge of optimizing a light-measurement device's optics for cost efficiency and performance. My recent project involved similar ray geometry analysis and lens selection to achieve desired light concentration. Could you share more details about the detector's field of view and any specific wavelength requirements to better tailor the solution? Regards, Yogesh Kumar

@johnedwardl

Hi, I will design a new light path for your measurement device that uses a single, low-cost lens to achieve the required 30 mm to 5 mm concentration. Leveraging my experience with optical design, I’ll analyze the ray geometry and perform the necessary calculations to ensure we maintain the detector's field of view while avoiding vignetting and excessive aberrations. I’ll provide a detailed justification for the lens choice, along with ray-trace or analytical data demonstrating energy throughput and spot diameter across the visible spectrum. A mechanical drawing or step file will be included to position the lens accurately for 3D printing or machining. Additionally, I'll evaluate the optical efficiency compared to your current setup, giving you a clear understanding of the cost-performance trade-off. I am ready to start immediately and ensure the design meets your specifications for prototyping. Thank you.

@SkillCrafts

I understand you're seeking to replace a costly dual-lens optical path with a single, cost-effective catalogue lens while maintaining critical light concentration from a 30mm entrance to a 5mm detector area. My experience optimizing similar systems for reduced component count and improved throughput aligns perfectly with this objective. My approach will involve detailed ray tracing using Zemax OpticStudio. I'll analyze various commercially available singlet lenses (e.g., plano-convex, biconvex) with appropriate focal lengths and diameters to achieve the desired magnification and image quality. Calculations will focus on transmission efficiency, spot size at the detector plane, and ensuring the entire light cone remains within the detector's field of view, considering aberrations and potential vignetting. Have you identified any preferred lens manufacturers or specific focal length ranges to explore initially? I'd be happy to discuss my preliminary findings and proposed lens candidates in a brief call.

@adnanmalik756

Hi, I see you're looking to redesign the optical path of your light-measurement device to use just one lens instead of two. This is a great move for cost efficiency while still needing to maintain the same 30 mm to 5 mm concentration. I have over 7+ years of experience in optical engineering, which includes working with lens design and ray tracing. My approach would involve analyzing the ray geometry to select an appropriate off-the-shelf lens from Zeiss or B&M Optik that meets your specifications. I would perform calculations to ensure the light transmission and spot size are optimal, while also creating a simple mechanical drawing for accurate placement. I'll make sure to provide the necessary data and calculations to back up the choices made. One question I have is: do you have any specific constraints on the type of lens material or coating for the new setup?

@edgardop86

Hi there, Tight deadlines on an optics redesign need a simple plan, not extra noise. This one lens solution project aligns neatly with my capabilities. Here's a possible roadmap: - Day 1-2: Review your current setup in detail, focusing on exact geometries and detector specs. - Week 1: Dive into available Zeiss/B&M Optik catalogues, selecting promising single lens candidates, and begin initial analytical ray tracing to narrow down options. - Week 2: Refine the chosen lens design using a tool like Zemax/OpticStudio, running simulations for throughput, spot size, and vignetting, specifying any necessary diffusers or baffles. - Week 3: Finalize all calculations, prepare the mechanical drawing/step file with tight tolerances, and deliver the efficiency comparison. The deliverables outlined are well within my familiar territory. I'm ready to walk through the scope and timing in chat whenever that's helpful-thank you.

@marcosfermin

Howdy! I've spent years designing optical and sensor integration pipelines for measurement hardware, and your 30 mm to 5 mm concentration problem is exactly the kind of constrained single element optics challenge I enjoy solving analytically before touching any physical parts. My approach would start with a plano convex or best form singlet from the Zeiss Milvus or B&M Optik catalogue, selected for a focal length in the 35 mm to 50 mm range that satisfies the 6:1 magnification ratio your geometry demands. I would run a full paraxial ray trace in Python using the Raysect library alongside a sequential analytical model to confirm the back focal distance, entrance pupil placement, and marginal ray height at the detector plane, then cross check spot size across the visible spectrum (450 nm to 700 nm) to quantify chromatic blur and confirm it stays within the 5 mm active area with margin. Thank you. Marcos.

@mayr81

Hello, I can redesign your optical path into a single-lens solution that maintains the 30 mm → 5 mm concentration while minimizing cost and preserving optical efficiency. I will analyze the ray geometry, evaluate candidate catalog lenses (Zeiss / B&M Optik), and validate spot size, vignetting, and throughput using analytical calculations and ray-tracing (Python/OpticStudio equivalent). The final output will include a justified lens selection, optical performance comparison with your current system, and a manufacturable mechanical layout for alignment and mounting. Cora

@pebitechnologies

Hi, Before selecting a lens, I'd want to understand the current optical path dimensions, detector specifications, and wavelength range. Reducing a two-lens system to a single catalog lens sounds simple on paper, but the trade-offs usually show up in spot size, throughput, and aberration control. The existing geometry will determine whether a single-element design is realistic. I'd be happy to review the current design files and discuss the feasibility before making recommendations.
