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
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.
After six months of intensive collaboration, STC developed its anti-laser filter with input from experts such as optical consultant Fang Jian-Tai, laser technology specialist Chen Pin-Hong, and Original Photography Studio, which provided a Canon R3 for burn-in testing. The filter successfully protected the camera’s CMOS sensor against direct 6.5W laser exposure from 20cm. This achievement was showcased at the 2024 Taipei Photography and Audio-Visual Equipment Exhibition (Booth J1111), drawing significant interest from photographers who had suffered laser-related sensor damage.

In Taiwan, a 2017 incident involved a pilot being targeted with a blue laser pointer at 2,000 feet while landing. By 2018, Taiwan’s legislature passed amendments to the Civil Aviation Act, imposing fines up to NT$900,000 or seven years of imprisonment for targeting aircraft with laser beams, with the death penalty applicable if fatalities occur.
In the U.S., the Federal Aviation Administration (FAA) has enacted similar measures, including public awareness campaigns, strict penalties, and requiring protective measures for aircraft, such as anti-laser coatings for cockpit windows. These coatings sometimes cause a slight red hue in low-green environments, prioritizing safe flight operations over visual fidelity.
