I manufacture professional dental loupes and now need a specialist to engineer the next-generation optical system for our lineup. The core brief is straightforward: produce a 3×–5× magnifier that delivers a crisp, wide field and can be dialed through several power steps for adjustable magnification. What I need from you • A full lens prescription and layout—prismatic or Keplerian, whichever meets the performance targets—modelled in Zemax, Code V, or an equivalent ray-tracing package. • Recommendations on glass types, coatings and lightweight housings so the finished loupe remains comfortable for all-day wear. An anti-reflective, easy-clean coating is strongly preferred. • Tolerance, MTF and illumination analyses that prove the design hold...

I’m rebuilding the optics in my light-measurement device. Right now the module relies on two lenses, a circular diffuser plate, and an aperture to guide visible light from a 30 mm entrance circle down to the 5 mm active area of the detector. It works, but the cost of the double-lens stack is no longer acceptable. Your mission is to engineer a new light path that achieves the same 30 mm-to-5 mm concentration using just one readily available, low-cost catalogue lens. Please analyse the ray geometry, calculate transmission and spot size, and confirm that we stay within the detector’s field of view while avoiding vignetting or excessive aberrations. If a minimal diffuser or baffle is still required, specify it, but the core goal is a single-element solution. I will need: • ...
