Precision optical components engineered for the demanding requirements of medical and life science instrumentation.
Medical device optics must meet stringent material safety standards. Substrate materials must be biocompatible, coatings must not outgas harmful substances, and all materials must be compatible with sterilization processes used in clinical environments.
Endoscopes, handheld diagnostic devices, and portable imaging systems require optics in extremely compact packages. Achieving diffraction-limited performance in miniature form factors demands precision manufacturing and careful optical design.
Fluorescence microscopy, pulse oximetry, and optical coherence tomography (OCT) systems rely on high transmission at specific wavelengths across the visible and near-infrared spectrum. Every percentage point of transmission loss reduces signal-to-noise ratio.
Reusable medical optics must withstand repeated sterilization cycles — autoclaving, ethylene oxide, or chemical disinfection — without degradation of optical performance, coating adhesion, or surface quality.
Medical device manufacturers operate under ISO 13485 and FDA regulations. Optical components must be supplied with full documentation, material traceability, and consistent quality to support your regulatory submissions.
350 nm – 2 μm
General-purpose optical glass for visible-light medical instruments. Good transmission, cost-effective, compatible with standard AR coatings. Suitable for non-sterile applications.
180 nm – 2.1 μm
High UV transmission for fluorescence and spectroscopy applications. Excellent thermal stability for autoclave-compatible components. Low birefringence for polarization-sensitive systems.
150 nm – 5.5 μm
Exceptional hardness and chemical resistance. Ideal for applications requiring repeated sterilization or exposure to aggressive cleaning agents. Biocompatible per ISO 10993.
VIS range
Lightweight, cost-effective for disposable or high-volume applications. Suitable for lower-performance requirements where glass is not necessary.
Medical imaging optics occupy a unique intersection of performance requirements. Unlike industrial optics where cost-per-unit often dominates, or research optics where performance alone matters, medical optics must simultaneously satisfy optical performance, biocompatibility, sterilization compatibility, and regulatory traceability — often within extremely compact form factors.
Consider fluorescence microscopy, one of the most widely used imaging modalities in life sciences. The optical path typically includes an excitation filter, a dichroic beamsplitter, and an emission filter — each optimized for the specific fluorophore being used. The excitation filter must pass the excitation wavelength with high efficiency while blocking all other wavelengths. The dichroic must reflect the excitation band with >95% efficiency while transmitting the emission band. The emission filter must block residual excitation light to OD6 or better while passing the emission band.
For endoscopic applications, the constraints are even tighter. Ball lenses and gradient-index (GRIN) lenses must deliver diffraction-limited performance through apertures measured in millimeters. The optical design must work within the physical envelope of the endoscope while maintaining image quality across the full field of view. And because endoscopes contact biological tissue, every material must be biocompatible and sterilizable.
Optical coherence tomography (OCT) systems present another set of challenges. These interferometric imaging systems require optics with extremely low wavefront distortion and high transmission across a broad bandwidth (typically 800-1300 nm for ophthalmic OCT). Any dispersion mismatch between the reference and sample arms degrades axial resolution. The optics must maintain performance over temperature variations encountered in clinical environments.
