Dichroic filter EUROLITE 41906657 orange frost 165x132 mm

The EUROLITE orange frost dichroic filter (165 x 132 mm) is a glass optical filter coated with dichroic layers to transmit warm orange tones while reflecting unwanted wavelengths and heat. It is intended as a color-correcting and effect element for stage, studio and architectural luminaires that accept rectangular glass inserts of similar size. The frost finish softens the projected beam, producing a more even wash without hard edges while preserving the long-term color stability and heat tolerance associated with dichroic-coated glass.

Advantages

This dichroic glass filter delivers consistent orange coloration with minimal color shift over time thanks to the multilayer coating process. The frost surface diffuses light to reduce hot spots and create a smooth wash. Its glass construction offers higher heat resistance and stable optical properties compared with many plastic alternatives, and the rectangular format fits fixtures designed for inserts of comparable dimensions.

Suitable for

• Stage and theatre luminaires that accept 165 x 132 mm glass inserts
• Studio lighting where warm orange color correction is required
• Architectural or display lighting for soft, colored washes
• Photography and film rigs needing durable dichroic colour filters

Key specifications

• Material: dichroic-coated optical glass with frost finish
• Colour effect: orange (frosted diffusion)
• Dimensions: 165 x 132 mm
• Optical behaviour: transmits target wavelengths for orange tones, reflects infrared/heat
• Mounting: designed for fixtures that accept rectangular glass inserts

How to use

Install the glass filter into the fixture’s filter frame or holder that matches the 165 x 132 mm size, ensuring the frosted surface faces the light-emitting side if a diffused beam is desired. Secure the filter according to the luminaire manufacturer’s instructions and verify that the fixture’s operating temperature is within the filter’s rated tolerance. Handle the glass by its edges or wear gloves to avoid fingerprints on the coated surface; clean only with manufacturer-recommended glass cleaner and a soft lint-free cloth.

Usage recommendations

For prolonged service life, avoid exposing the filter to direct contact with high-temperature lamp envelopes and ensure adequate fixture ventilation. Store flat in a clean, dry place and protect from mechanical shock. When replacing or cleaning, inspect the coating for scratches or delamination before reinstalling.
