NOTCam Ks filter
|NOT filter number:||207|
|Marking on filter edge:|
Transmission curves: gif image, ASCII data
Note:These transmission data have been scanned from the manufacturer's hardcopy. They are probably good to a couple of %. Details of the scanning procedure are not known, but the scan was made at ambient temperature. A small shift to the blue will be effected at operating temperature.
Notes: Purchased as part of the Gemini NIR filter consortium.
About the Ks filter: The Ks (K-short) filter has a shorter
cut-off wavelength than the standard K band in order to lower the
thermal component of the background (developed by M. Skrutskie). The cut-on
wavelength of Ks is the same as for K, which makes it more
useful than K' at "not very dry sites", although the passband becomes
a bit narrower than for K.
