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.
The Clip Filter is an STC world-first innovation, designed specifically for mirrorless cameras. Its durable and robust structure ensures the filter remains securely positioned in front of the sensor without shifting or falling. It provides added protection for the CMOS sensor and can be easily installed or removed as needed.
For Sony full-frame mirrorless cameras, variations in internal chamber height necessitate different spacer thicknesses. For some older models with curved grooves on both sides, the effectiveness of CMOS protection may be slightly reduced.

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.
Shipping Notice
Our Products are manufactured in Taiwan(R.O.C), not China. After packaging the products in cartons, we ship them via international couriers such as DHL or OCS. Import taxes for each country are not included in our sales responsibilities; if you have concerns regarding customs duties, please contact your local customs office.
If a shipment is returned due to failure to pick up the package or refusal to pay customs duties, we will charge the additional return logistics fees. Order cancellations under such circumstances will also have the relevant costs deducted.
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.

Facing the camera sensor upward, you can install the clip filter with only hand or our magnetic tooling (included) into the camera body in front of the shutter curtain. Screw on the lens and you can start shooting without extra setting needed. The clip filter stays firmly in front of your camera shutter so it can protect your sensor at the same time, it avoids dust and dirt while changing lenses outdoor. It’s easier and less risky to clean the clip filter than to clean your sensor.
STC Interchangeable clip filter made of aerospace grade aluminum alloy, metallic mist black anodizing and chamfer processing made it gently and firmly lies in camera body and will not abrade the inner parts. The patented glass assembling design is tolerable to thermal expansion which reduces glass flatness change, thereby preventing telephoto images focusing.
All our filters use STC’s exclusive nanocoating technology for the best optical quality. Our Laser Shielding , Sensor Protector, Stat Mist, Cine Mist, Neutral Density (ND), Astro (light pollution) series, IR-Pass (590nm/720nm/850nm) and UV-IR cut filters all carry a double-sided hydrophobic, anti-smudge and antistatic nanocoating to enhance or block transmission in all kinds of particular spectrums.
