FAQs

Can standard interference filters be used as di...

Generally, no. It is not recommended to use standard interference filters as dichroic mirrors to reflect blocked wavelengths, although they might seem similar in construction. While both use thin-film dielectric...

Do optical filters exhibit autofluorescence whe...

Yes, many optical filters do exhibit autofluorescence when exposed to Ultraviolet (UV) light. When high-energy UV light strikes certain optical materials, those materials absorb the photons and re-emit them as...

Is absorption data available for the blocked ba...

Interference (or dichroic) filters from Syron Optics are constructed using alternating microscopic layers of thin-film dielectric coatings. They utilize thin-film optical interference to selectively transmit target wavelengths while reflecting the...

Can optical filters be cascaded to increase out...

Yes, optical filters from Syronoptics.com can be cascaded to increase out-of-band attenuation. Optical Density (OD) is a logarithmic measurement, meaning the total out-of-band attenuation of cascaded filters is theoretically additive....

Are volume discounts available for bulk purchases?

Yes, volume discounts are available for bulk purchases at Syronoptics.com. The discount generally depending on the specific quantity and the specifications of the optical filters you are ordering.  

What are the recommended methods for mounting o...

Mounting optical filters correctly is critical to maintaining the integrity of the light path. Improper mounting can lead to mechanical stress, which causes wavefront distortion, or alignment issues like tilt...
