Custom Dermatoscopy Lens Design
Budget: ₹1,000 – ₹3,000 INR
I need an experienced optical engineer to create a complete lens design dedicated to a dermatoscopy‐grade microscopy system. The goal is a compact objective that delivers crisp, color-corrected images of skin structures at high magnification, suitable for integration into a handheld digital device.
Scope of work
• Model and optimise the lens in Zemax (or equivalent) to meet the following targets: 20–30× effective magnification, ≥90 lp/mm resolution at the sensor, working distance ≥15 mm, field of view ~10 mm, minimal chromatic and field curvature.
• Confirm manufacturability with standard glass catalog parts wherever possible and flag any custom elements early.
• Provide tolerance analysis and recommend coatings to maximise throughput under LED illumination.
• Supply final optical prescription, fully annotated Zemax file, tolerance report, step-file of mechanical envelope, and a short design note explaining performance trade-offs.
Acceptance criteria
1. Zemax optimisation achieves stated resolution across ≥80 % of the field.
2. MTF plots and spot diagrams demonstrate compliance.
3. All files open and rebuild without errors.
If you have a solid track record in microscopy lens design and can deliver the above documentation, I look forward to working together.
