Temperature Controllers

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.

 

See the General and Technical Information pages for further information on the influence of temperature on spectral characteristics.

 

Please note: The standard oven accepts a 50mm dia. filter, but we can provide a reducer to accomodate any smaller size. Please contact our technical sales department for a quotation.
