In doing so, we comply with international standards in accordance with ISO 9001 for quality management. Please find below a short description of our Anti Reflective Broad Band AR Coating (BBAR) Within an optical system, many optical parts need to apply some combinative thin film layers on the substrate surface which enhance the transmission or reflection properties of the parts. The quality of the coating depends on the layers. PHYO OPTICS can apply the coating as: Anti-reflective (AR), High Reflective (HR), Partial Reflective (Beam splitter), and Filter, polarizer, and mirror coatings. With the state of art coating facilities, coating is the advantage area for the company. ?? We supply the following coating:
Anti-Reflective Coating
Reflective Coating
Beam splitter
Filter
OEM special coating
Anti-Reflective Coating (AR) means to reduce the absorption or reflective of the light when get through the optical parts. normally PHYO offer the MgF AR coating, Multi-layer AR, and Broad band AR (BBAR). Single wavelength, Dural Peak, V type still available for the AR coating. In order to get a flat response over a certain spectral range, some of the optical system needs to be coated with broadband antireflective coating. The BBAR high in efficiency at more than one wavelength.
Substrate Material: H-K9L, Fused Silica, Sapphire or similar Incident angle: 0°<AOI<15° Designed Wavelength range : 350nm < ? < 2400nm Normally R<2% can be reached, some case R<0.9% workable. Singed sides, double sides available. Customized coating available. Our capabilities include:
