Colour Filters - Glass Type - Long-pass - 25 mm diameter
|
| Solid Colour Glass filters achieve considerably higher blocking densities than dichorics and are used within selective wavelength absorption. The filters spectral transmission properties are uniform over the entire aperture and the following thicknesses have been chosen for average blocking percentages in relation to their type. If you require a different wavelength block, we can simply calculate the thickness necessary to achieve your required wavelength. Our photonic filters (530FCS5050) are used with silicon detectors or cameras to adapt the spectral response. The following list of Schott Colour Glass filters are of the circular long-pass type with a diameter of 25mm.
Specifications: | Material: | Schott Colour Glass | | Diameter: | +0.0 / -0.25 mm | | Length / Width: | ± 0.25 mm | | Thickness: | ± 0.20 mm | | Surface Quality: | <60-40 scratch/dig | | Flatness: | <2.5λ over 90% test area | | Parrallelism: | <3 arcmin | Note Wavelength listed in table is transition wavelength (T=Tmax/2) for long-pass and short-pass filters, and peak for band-pass filters.
