2025 Reflective Laser Shielding Optical Filter

Latest Spotlight for 2025: STC’s Reflective Laser Shielding Optical Filter

STC has dedicated six months of research and experimentation to address the damage caused by laser effect lighting to camera and smartphone sensors in stage and event environments. The result is a groundbreaking nano-coated optical filter capable of reflecting 75% of laser energy. Unlike traditional absorption-based ND filters, which store energy and allow light to pass through once saturated, STC's filter utilizes reflective technology, preventing energy build-up.

Conventional image sensors can tolerate up to 5000mW at a single point. In real-world tests, the STC filter withstood up to 7000mW from a laser beam at 50cm for 0.5 seconds, effectively protecting mirrorless camera sensors without damage. Additionally, the filter maintains a consistent visible light spectrum (400-700nm) without color distortion.

Features

  • 75% Laser energy reflection
  • Nano-Coated Reflective Technology: Reduces energy accumulation.
  • Consistent with the visible light spectrum of 400-700nm, it ensures no color shift.
  • The light reduction level is approximately ND4 (around -1.7~-2.0 EV).

Protection Scenarios

When your footage shows interference from laser spots, this reflects the filter’s protective capabilities, safeguarding your camera’s sensor. While some visuals might be compromised, your protected camera will remain functional to capture future, more remarkable moments.

Disclaimer

Usage conditions, including distance and duration of laser exposure, vary significantly. If damage occurs due to excessive laser power or prolonged exposure (as energy accumulates over time), it may exceed the 70% reduced threshold and the camera sensor’s tolerance limit. Each camera model has different limits; consult your camera manufacturer for details. STC assumes no liability for damage under these circumstances. Please fully understand the product’s capabilities and limitations before purchase.

Note:
1.Due to the reflective coating technology, diffraction artifacts may appear under certain light sources; this is not a product defect.

2.The light reduction level may vary slightly due to coating variability between production batches. This is not a product defect.

About This Product

Features

 Laser Safety Notes (Refer to User Manual)
  • 1.According to the U.S. FDA Laser Safety Classification (aligned with Taiwan's standards), visible continuous lasers exceeding 500mW fall under Class IV, posing risks of skin burns and fire hazards.

  • 2.A 200mW visible continuous laser can ignite a match at a 15cm distance. Higher-power lasers can easily damage the human eye. Laser power diminishes with distance due to atmospheric attenuation, but for safety, crowd-facing beams at performance venues should not exceed Class 3B limits (below 500mW).
