OptiGrate Corp is a fast growing, innovative technology company with leading positions in design, development and production of holographic optical elements. For over a decade OptiGrate has manufactured a full range of volume Bragg gratings (VBG) in inorganic photosensitive silicate glass and supplied holographic optical elements to OEMs, government contractors, and research institutions. OptiGrate's key product lines include VBGs for laser locking and stabilization of diode, fiber, and solid state lasers; most compact stretchers and compressors for high energy ulra-short pulsed laser systems; ultra-narrow band optical notch and bandpass filters for low frequency Raman systems; gratings for spectral and coherent beam combining, etc. OptiGrate is proud to have more than 400 customers on 5 continents. It was elected one of the 50 Florida Companies to Watch in 2011 and received the Small Manufacturer of the Year award in 2012 from the Manufacturers Association of Central Florida. OptiGrate provides competitive salaries, full benefit package, and great professional growth opportunities.
