The XTM-50 tunable filter is the perfect tool for laboratory use. Its optical performance is identical to the XTA-50 as it is based on the same optical system. The wavelength tuning and bandwidth adjustment are manual through micrometers. All versions of the XTA-50 have their manual equivalent in the XTM-50 family.
