Our IR Filters are deposited by sputtering, using our ‘Rockard’ © technology, traditionally thermal evaporation has been used for IR filters. Some of the benefits of sputtering are outlined below Highly durable coatings suitable for the toughest environments. Extremely low temperature shift. Reduced passband ripple for an even response. High blocking efficiency to increase signal to noise ratio.
