Transmittance Measurement Kits
Transmittance measurement kits are integrating sphere assemblies for measuring optical systems at one infinite conjugate. The integrating sphere collects the total flux transmitted through the optical system over a 25-mm diameter portion of the entrance pupil. An iris diaphragm assembly is provided in each kit to reduce beam diameter from the test system’ s collimator. The iris diaphragm mounts in front of the optical system under test. The 100% transmittance baseline is determined by initially placing the integrating sphere directly in the collimated beam.
TK-1100 Visible Transmittance Measurement Kit
This kit includes a 100-mm diameter-integrating sphere with white reflectance coating, a 25-mm diameter beam entrance port, photopic response detector, and photometer read-out electronics. The integrating sphere assembly replaces the image analyzer used with the test system when measuring transmittance.
