The camera sees through our glass.
A teleprompter sits inside the lens's light path, so our high-transmittance beam splitter is designed to protect clarity and color before the image reaches the sensor.
Optics decide image quality before the camera can correct it.
The lens captures light only after it passes through the glass, so the beam splitter sets the ceiling on every image.
A low-quality splitter does more than dim the picture. It shifts different colors by different amounts, so the camera cannot fully correct the image afterward.
Measured, not claimed.
Our beam splitter is verified against the CIE1931 colorimetric standard, so its color rendering, color temperature and transmittance are tested results, not marketing adjectives.
CRI ≥ 99, measured 99.3 for broadcast-grade color rendering.
R9 ≥ 95, measured 95.7 to preserve demanding red tones.
Measured color temperature tracks the 5500K Planckian curve closely.

The coating that protects the picture.
Our beam splitter carries a vacuum sputter-deposited multilayer dielectric coating, where each layer is tuned for a specific optical job.
Anti-reflection function
The coating raises transmission and suppresses ghosting and double images, so the prompt remains legible without contaminating the camera image.
Color-neutral tuning
Transmitted and reflected light stay neutral, which keeps the measured color numbers honest in real production use.
Durable in broadcast environments
The coating is oxidation-resistant and fungus-resistant, so optical performance stays stable in humid, high-use studios and venues.
