Compact Scientific Digital Cameras Chapter 3: Setup & Installation
Rev C, August 27, 2021 Page 15
3.5.1. Description of Components
• Lens Cap: A protective cover that should always be installed during movement or shipment, and also when
the camera is not in use. Included but not shown here.
• Protective Window: Unless otherwise requested, a protective glass window is installed and held in place
by a retaining ring.
o Users may, at their discretion, remove the protective glass window, or replace it with a custom
optical filter. When using a CS-mount or C-mount adapter the maximum filter thickness is 0.050"
(1.270 mm) with Ø1", otherwise the maximum filter thickness is 0.173" (4.4 mm) with Ø1".
o CMOS imagers have responsivity that extends beyond the visible range, into the NIR spectral
range. When installed, an NIR blocking filter cuts off light at higher wavelengths.
o All monochrome Compact Scientific cameras are configured with an AR-coated protective window.
For imaging that is limited to the visible region, users may install an NIR blocking filter in its place.
o All color models are configured with an NIR blocking filter as the protective window. The NIR
blocking filter is installed in order to achieve realistic colors in white light.
o See Chapter 7 for more information on both types of windows. See Section 3.6.1 for instructions
related to removing and replacing the glass window.
