Thorlabs offers two filter kits that bundle our most popular longpass and bandpass colored glass filters. The FGK01 Colored Glass Filter Kit contains three filters from our bandpass family and seven from our longpass family. The Ø25 mm filters are premounted in an SM1L03 lens tube that is engraved with the part number and bandpass region (for bandpass filters) or cut-on wavelength (for longpass filters), and ship in a KT01 Storage Box with labeled slots to aid organization. The FGK01S Colored Glass Filter Kit contains the unmounted, square 2" x 2" counterparts to the filters in the FGK01.

FGK01 Contents	FGK01S Contents	Bandpass Region	Transmission Plot
FGS900M	FGS900S	315 - 710 nm
FGB37M	FGB37S	335 - 610 nm
FGUVM	FGUVS	325 - 385 nm
FGL400M	FGL400S	400 - 1800 nm
FGL495M	FGL495S	495 - 1800 nm

If you currently own individual filters and would like to have a box to store them in when not in use, consider our storage boxes. These are the same storage boxes that our kit lenses arrive in. There is one box (KT01) designed for mounted Ø25 mm round filters and a second (KT03) for the unmounted 2" x 2" filters.
