2025 Reflective Laser Shielding Optical Filter - High-Performance Laser Protection Lens for Industrial & Scientific Applications

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 filter surface 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.

A Reddit user reported that their smartphone’s image sensor was damaged after being exposed to the LiDAR system of a certain car brand. This system, used in ACC (Adaptive Cruise Control) and based on pulsed ToF (Time-of-Flight) laser technology, may pose a risk under specific conditions.

According to an investigative report by Car and Driver, LiDAR systems in the U.S. are subject to strict regulations on laser beam intensity and are considered safe for the human eye. However, damage may occur if a smartphone's telephoto lens is activated and placed very close to the LiDAR source, where the concentrated beam may pose a risk to the sensor.

LiDAR systems typically operate with short-wavelength infrared lasers ranging from 905nm to 1550nm, with angular resolution as narrow as 0.1°. STC’s Laser Shielding Filter, developed with the latest optical coating technology, is engineered to effectively reflect this wavelength range and provide comprehensive protection for smartphone camera modules.

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.
