Case Study: Structured-Light Stereovision System for Parcel and Package 3D Dimensioning
Optics for Hire designed and prototyped a structured-light stereovision system for real-time 3D package dimensioning on warehouse conveyor lines. The project included ZEMAX optical modeling, custom subpixel stereo matching algorithm development in MATLAB, and bench-top prototype validation, achieving 0.9 mm depth accuracy across a 700–1500 mm working range within a 14–16 week engagement.
Case Study: Custom VIS-NIR Dual-Band Imaging Lens for Fluorescence-Guided Surgery
Custom VIS-NIR Dual-Band Imaging Lens for Fluorescence-Guided Surgery
Optics for Hire designed a custom 35 mm f/1.65 imaging lens that simultaneously focuses visible and near-infrared light for a fluorescence-guided surgical camera. The 7-element design reduced chromatic focal shift by 54% compared to the catalog lens it replaced, enabling real-time tumor visualization without refocusing.
3 Strategies for Field Lens Development and Design
Field lenses are a basic element in optical design, to understand their role in an optical system it’s important first to understand the definitions of Field-of-View (FOV). Generally speaking, FOV is the maximum size of an object that an optical system can create an image of. The FOV is related to the size of the […]
Powering advanced optical design with liquid lenses
Liquid lenses, are a type of optical lens that have a tunable focal length by shaping a liquid electronically. These lenses can be based on voice coil actuation, or based on electrowetting technology, which involves manipulating the surface tension of a conductive liquid droplet by applying an electric field. The core component of an electrowetting-based […]
