1064nm Optical Filter Coating Colour Seperating Dichroic Coating
Dichroic Filter Coating, Colour Seperating Thin Film Optical Coating Overview: Dichroic Filter Coating is a thin film optical coating usually added by vacuum deposition on glass substrates, intending to reflect a specified range(s) of wavelengths and transmit a different specified range(s) of wavelengths at a specified AOI, typically 45 degrees. It is commonly used to split spatially overlapping beams of different colours. One special feature of Dichroic filter coating is the
Bandpass Thin Film Optical Coating 1500nm Optical Interference Coatings
Bandpass Interference Coating, Bandpass And Laser Line Filter 355 - 1600nm Thin Film Optical Coating Overview: Bandpass interference filter coating selectively transmits a narrow range of wavelengths while blocking others. Our state-of-the art sputtering coating technology allows us to produce filters in UV, VIS and IR center wavelengths with deeper blocking, higher transmission, and steeper slopes.

12.7mm Optical Glass Filters Birefringent Lyot Filter For Solar Astronomy
Lyot Filter, Birefringent Filter, Birefringent Tuners Overview: A Lyot Filter (Birefringent Filter), named for its inventor Bernard Lyot, is a type of optical filter that uses birefringence to produce a narrow passband of transmitted wavelengths. Lyot filters are often used in astronomy, particularly for solar astronomy. Lyot filters (Birefringent tuners) for wavelength tuning of lasers are made of crystal quartz (Transmission ranges: 200 nm-2700 nm) or MgF2 (Transmission
50x50mm Colored Optical Glass Filters Longpass For Environmental Testing
Colored Glass FilterOverview:Colored glass filters are high quality absorption filters made of colored glass. They allow certain wavelengths of light to pass unimpeded, while blocking other wavelength ranges to a designated extent. Rather than using thin film coatings to achieve filtering effects, these filters rely on the absorption and transmission properties of the color glass. Precision can be achieved through careful control of the thickness of the material as well as of
400-1100nm Optical Glass Filters N-BK7 Reflective Neutral Density Filter
Reflective Neutral Density (ND) Filter Overview: Reflective Neutral Density (ND) Filters provide uniform attenuation over the broad spectral range from 400 to 1100 nm. Reflective ND filters consist of an N-BK7 glass or UV fused silica substrate with a metal (Inconel) coating deposited on one side. Inconel is a metallic alloy that ensures flat spectral response from the UV to the near IR. To prolong the lifetime of reflective ND filters, we recommend using non-contact cleaning
Dichroic Optical Mirrors Combining Wavelengths Fused Silica Substrate
Dichroic Mirror/Filter/Beamsplitter, Separating Or Combining Wavelengths Overview: A Dichroic Mirror/Filter/Beamsplitter, also down as a dual-band mirror, dual-wavelength mirror, or dichroic reflector, is a specialized mirror which has different optical properties at two different wavelengths. For instance, a dichroic mirror might be reflective below a cut-on wavelength, then transmissive at longer wavelengths. Dichroic mirrors are manufactured using electron beam deposition,
