Select a filter from the scroll menu.
One option is the Linear Ramp Filter (LRF). This filter provides a narrow band capability which is continuously tunable from 3710 to 9762 Angstroms. The FWHM of the LRF bandpass is about 1.3% of the central wavelength. The clear field of view for the LRF is about 10 arcseconds.
Currently we do not support multiple filters in the beam (e.g. F555W + POLQ).
