Medical & Life Sciences

OSI Optoelectronics is one of the largest OEM solution providers in life sciences.  We design and manufacture chips, modules, and complete box builds from concept to high-volume production.  Many of our worldwide facilities are FDA registered and audited, and our manufacturing is ISO 13485 and QSR / GMP compliant. 


Our photodiodes and optoelectronics modules play a significant role in many medical diagnostics and monitoring devices.   We are a designer and manufacturer of photodiodes and optoelectronic components for medical equipment, including patient monitoring systems, pulse oximeters, CT scanners, and bone densitometers. Additionally, the company manufactures complete turn-key devices for glucose monitoring.

With many years of experience providing the best standard and custom X-ray detector devices for the medical field, our proprietary detector/scintillator crystal devices offer outstanding track records of reliability. Our broad manufacturing experience with X-ray detector modules has provided the high level of R&D and engineering necessary to create the best product for any X-ray scanning application. We are the largest supplier of 2-dimensional back-illuminated arrays for CT scanners.

Life Sciences

Of the numerous applications in the life sciences, fluorescence detection is where our sensors excel.  In fluorescence microscopy of tissues and cells and automated sequencing of DNA, by labeling or tagging antibodies or DNA molecules, the fluorescent label is excited by a UV source, and the identity of the base terminating the molecule is identified by the wavelength of the emitted light.  Many biological molecules have an intrinsic fluorescence that can sometimes be used without attaching a chemical tag.  These systems use high-intensity light sources to excite fluorescence from samples under observation, optically filtered, and then detected by a silicon photodiode.  

Other life science applications include flow cytometry, blood chemistry, and food analysis.  In the latter application, light reflectance is spectroscopically measured from many types of chemicals such as sugar, protein, water, and fat.  The same wavelengths are also utilized for high-speed grain sorting.  UV excited fluorescence also provides a method for detecting the presence of carcinogenic and bio-contamination.
