Dichroic Filters

Dichroic filters coated with hard dielectric thin-films that you will see different colors when light passing through the dichroic filter.

Category: Glass filter

Description

We offers dichroic filters coated with hard dielectric thin-films. The dielectric thin-films filter out the unwanted regions of visible spectrum and let the light of certain wavelength transmit so that you will see different colors when light passing through the dichroic filter.

Planetary-runningcoating machine lets thin-films evenly attach to the glass substrate which guarantees consistency of optical specification from different pieces and different batches.

With Ion Assistant Deposition (IAD), the thin-films will firmly attach to the glass substrates with great density which makes the filters greatly resistant to the environmental degradation.

There are over 70 colors available which offers flexibility for you to choose the most suitable one for you.

For your unique project we are able to develop the required color as well.

Glass Substrates

The glass substrates are the most fundamental and critical for making optical filters.
In order to ensure the quality, KUPO Optics uses optical grade glasses to produce perfect filters.
