OPTICAL FILTERS AND COATINGS - Tower Optical - #1

Text version of the page

Tower customfilters cover applications for biomedical bandpass, narrow bandpass, broad banpass or long pass. Using ion-beam sputtering together with volume manufacturingmethods, Tower is able to offer cost-effective solutions. 18 561-740-2525 • Fax 561-740-2518 sales@TowerOptical.com • www.TowerOptical.com Cage Code: 1N2U3 SDVO-SB ITAR Compliant Optical Filters and Coatings Custom Filters Coatings • Highpower laser coatings: anti-reflection, reflective, partial reflectors, beamsplitters and polarizers • Metallic coatings Aluminum – UV and protected Silver – protected Reflectance >98% 800 nm to IR Gold – protected and unprotected • Broadband dichroic beamsplitter coatings • Polarizing beamsplitter coatings • Multi-wavelength and extended coatings • Anti-reflective coatings from UV to IR • Dielectric high reflective coatings high power • Filters short pass, long pass and bandpass filters The above coatings are available for wavelengths ranging from UV, VIS, and near IR, including laser wavelengths from 193 nm to 3 microns. Custom and specialized coatings available upon request. IBS Ion beam sputttered thin films for the most complex optical image. We can provide computer design of optical systems and thin film coatings.
