The performance of very narrow bandwidth interference filters can suffer significantly due to changes in ambient temperature or aging effects. Elevating the filter temperature can counterbalance aging shifts of up to 0.5nm and also provide a means of tuning the center wavelength to an exact value. As all our filters are bake stabilized to minimize any wavelength shifts with age, the regulated temperature controller provides protection against the influences of fluctuating ambient temperatures.
All of our filter ovens come with a universal oven controller, which will operate from 110 to 220 volts, 50-60 Hz and include plugs for US, UK, Australia and Europe.
Shipped in a sturdy, reusable weatherproof case.

The oven controller is required to operate the filter oven. For economic reasons, it may be desirable to purchase several filter ovens but fewer controllers, as dictated by your application.

The assembly kits include the necessary hardware to mount a filter into the filter oven as well as instructions for assembly. The windows supplied are broadband anti-reflective (AR) coated over the specified wavelength range for an average reflectance of ≤ 0.5% per surface. The substrate material is either Schott BK-7 or Fused Silica, as appropriate, and are polished flat to 1/4 wave and parallel to 30 arc seconds or better.
