Rosco Roscolux 121 Blue Diffusion Filter, 20x24" Sheet, Open Box

How the Rosco Roscolux 121 Blue Diffusion Filter Enhances Your Lighting Setup

The Rosco Roscolux 121 Blue Diffusion Filter, available as a 20x24" sheet, is an essential tool for achieving broad, even illumination in theatrical and photographic settings. This filter expertly combines a subtle blue tint with matte diffusion, ensuring a smooth and consistent light spread across cycs and drops, with a light transmission rate of 8%.

Rosco's Roscolux series is renowned for its durability and performance, crafted using a unique tri-extrusion technology. This process integrates three distinct layers, sealing the colored layer between two ultra-thin layers of clear film. This innovative design minimizes dye migration, significantly extending the filter's lifespan even under intense theatrical lighting conditions.

Globally recognized and sold under the name "Supergel" in international markets, Roscolux filters are the preferred choice for professionals. The line is predominantly made from co-extruded polycarbonate plastic, accounting for over 65% of the range, while the rest is composed of deep-dyed polyester. This construction contrasts with ordinary color filters, which merely have a surface coating of dye on clear polyester film, making them susceptible to heat damage and physical abrasion.

The Rosco Roscolux 121 Blue Diffusion Filter is available in convenient 20x24" sheets (50cm x 61cm) or larger rolls measuring 24x25ft (61cm x 7.62m). For those needing even larger dimensions, the Cinelux line offers rolls of 48x25ft (122cm x 7.62m), catering to a variety of professional lighting needs. Enhance your lighting projects with the reliability and superior performance of the Rosco Roscolux 121 Blue Diffusion Filter.
