NOTE: Filters are available for all wavelengths up to 320nm. Specifications for FWHM, peak transmission, and peak wavelength fall within peak wavelength ranges listed above.
Available Designs for Standard Bandpass Filters
Open-Faced - The open-faced design includes a substrate with an optical filter coating on one surface. Open-faced filters must be handled with care as the soft filter coating is exposed. Potential damage from moisture, atmospheric contaminants or handling can be reduced by sealing the
filter with a protective fused silica cover, as shown below (available above 190nm only).
Covered / Edge Sealed - Filters above 190nm may be supplied with a fused silica cover for protective purposes. As shown in the diagram, a spacer ring is placed between the substrates to form a small air gap, then the edges are sealed. This design enables the filter to be handled without risk of touching the delicate filter coating. Please note that covering a filter decreases its transmission by 2-3%.
Edge sealing adds approximately 0.010” (0.254mm) to the diameter of the filter. Total thickness for a covered and edge sealed filter is approximately twice that of an open-faced design. Exact dimensions are available from the Optics Sales Department.
Mounted - Open-faced or covered filters (without edge sealant) can be supplied in metal mounting rings, if desired. The rings are constructed from aluminum and are black anodized. Mounting a filter reduces clear aperture and increases the outside diameter as outlined below.
