Absolute Laser Protection & Precision Isolation: LTH1570 Ultra-Narrow-Band Filter
Engineered for 1570nm Laser Safety and Critical Signal Control
In high-power laser environments where safety and signal integrity are paramount, uncontrolled radiation poses severe risks to equipment and personnel. Manufactures delivers uncompromising protection with the LTH1570 Ultra-Narrow-Band Filter—a specialized laser protection solution designed for extreme rejection at 1570nm while transmitting critical signals with precision.
Critical Safety & Optical Performance
Centered at 1570nm (key for eye-safe telecom/industrial lasers), this narrowband filter features:
Ultra-High Optical Density (OD 8+) – Blocks >99.999999% of 1570nm laser radiation
Ultra-Narrow Bandwidth – Isolate adjacent communication channels or sensing wavelengths
Peak Signal Transmission (>90% in-band) for non-laser signals
Broad-Band Blocking (UV to SWIR) for multi-threat protection
Engineered for Extreme Environments
Constructed with rugged optical-grade substrates and advanced dielectric interference coatings, the LTH1570 guarantees:
Laser Damage Threshold >5 J/cm² (1064nm, 10ns pulse)
Thermal Stability – <0.01% shift per °C (0-60°C operating range)
Hardened Surfaces – MIL-C-675C compliant for abrasion/humidity resistance
Sealed Edges – Prevents delamination in vacuum/harsh conditions
Essential for systems requiring 1570nm laser safety or spectral isolation:
Laser Safety Eyewear/Goggles – Protect vision in medical/industrial laser facilities
Fiber Optic Network Protection – Shield sensitive receivers in 1550-1650nm telecom bands
LIDAR/Rangefinder Systems – Eliminate sensor blinding from ambient 1570nm sources
Medical Laser Systems – Ensure safe operation in dermatology/surgery equipment
Military/Defense Optics – Counter laser threats in EO/IR systems
Industrial Laser Processing – Protect imaging sensors in additive manufacturing
Customizable Protection Solutions
Available in standard sizes (round: Ø12.5-50mm, square: 5-50mm) and custom geometries. Options include:
AR coatings for dual-band systems
Wedged substrates to eliminate etaloning
Temperature-stabilized mounts
