How to Order

Go to the Sample Filters Catalog and select from the links displayed to see the list of available products in each group. Select the item number of interest from each listing to view a detailed description of the spectral and dimensional characteristics for each product.

Important Notes

• The number after the hyphen in the item number denotes the substrate material. (See Substrate Codes in the table below)
• An "E" at the end of the item number indicates that the filter can be custom sized to larger than the "standard" 1 inch diameter.  The pricing for filters is based on whole increments of 1" diameters (see pricing for further details). Custom Fabrication Standards are:  Dimensions +/-0.010", Surface Quality 80-50, edge bevel 0.0" - 0.020", edge chip max 0.015" (Standards may vary due to filter substrate and coating.  If a particular attribute is critical to application, please contact Customer Service).
• IR filters are attenuated out of band to less than or equal to 0.1% average transmission over as great a wavelength range as reasonably practical.  The filter description indicates the out-of-band wavelength beyond which the filter will require additional blocking if the detector used with the filter is still active.
• Dimensional measurements descriptions are nominal.
