PANIC Filters

All wavelengths and Full Width Half Maximum (FWHM) are in mircrons.
The filter parameters are at the working conditions (100 K and converging beam).
PANIC has four filter wheels, with capacity of up to 15 filters. There are currently 7 filters installed and 8 empty filter positions.
The filters are located in a converging beam. It is not possible to combine two filters on different wheels.
The optical design allows the use of narrow band filters (i.e. filters for which bandwidth ≤ 1% of central wavelength) without major degradation of their band pass.

Filter	Central wavelength	FWHM	50% cut-on	50% cut-off	T
Z	0.874	0.106	0.821	0.927	85%
Y	1.023	0.105	0.971	1.075	75%
J	1.247	0.157	1.169	1.326	84%
H	1.638	0.285	1.495	1.780	93%
Ks	2.150	0.328	1.986	2.314	95%
