Features
Standard Optics Sets with Edge Marked Optics
Our standard optic sets include a wood case organized by part number and key optic information. Confusion in identifying optical components is eliminated with edge marked part numbers on every optic in the OptiSet™. All edge markings are impervious to standard optical cleaning solutions.
Additive Optical Densities
Proper Orientation
-P Optics Sets with Laser Etched Optics
Our -P optic sets include a plastic carrying case with individual protective plastic cases for each optic marked with the part number and key optic information. Confusion in identifying optical components is eliminated with laser etched part numbers on the edge of every optic in the set.
Schott Borofloat Metallic ND Filter Set
Made with Inconel® metallic coatings on glass substrates, the Schott Borofloat glass ND filters provide spectrally uniform attenuation over the wavelength range from 0.4 to 2.0 µm. The reflective nature of the coatings helps reduce thermal effects when these filters are used with moderate-power lasers. Filters may be used individually or combined in series to obtain any desired density from 0.04 to 2.5.
UV Fused Silica Metallic ND Filter Set
The FR-ND and FS-ND UV Fused Silica neutral density filter sets consist of a logical assortment of filters packaged in a protective hard storage case. All filters are permanently marked with the optical density and are shipped with a transmission curve. The coating is deposited on one side of an ultra-pure UV grade fused silica substrate providing excellent transmission from the ultraviolet to the near-infrared (350-2000nm). Due to the absorptive nature of the metallic coating, use with high-power lasers should be avoided. Power levels less than 30 W/cm2 are advised.
Optical Crown Glass Metallic ND Filter Set
The FB-ND optical crown glass metallic neutral density filter Set consists of eight 25.4 mm diameter optical crown glass metallic ND filters packaged in a protective hard storage case. The metallic coating is deposited on one side of a cost-effective B 270 optical crown glass substrate, providing broadband attenuation for low-power applications. All filters are shipped with a transmission curve.
Absorptive ND Filter Set
The FS-3 and FS-3R neutral density filter sets consist of 9 absorptive glass. Compared to metallic ND filters, these absorptive filters are more economic and also reflect far less light toward the source which may be beneficial. Nevertheless stacking a large number of ND filters can still result in excessive undesired reflection due to Fresnel surface reflection. Due to the absorptive nature of the filter glass, use with high power lasers should be avoided. Power levels 1-5 W/cm2 are advised.
Germanium Metallic ND Filter Set
The FS-IR Germanium metallic neutral density filter set consists of 5 infrared filters. The filters are made of 80-50 scratch dig Germanium substrate and offer higher OD tolerance in the 2 to 5 μm wavelength range. The graph shows that the curve is almost flat over the full wavelength range.
