Precision Filtering at 903nm for Demanding NIR & SWIR Applications

In the expanding realm of near-infrared (NIR) and short-wave infrared (SWIR) photonics, signal clarity is non-negotiable. Scattered light and spectral noise undermine critical measurements in research, defense, and industrial systems. Manufactures delivers uncompromising performance with the LTH903 Ultra-Narrow-Band Glass Filter—engineered for exceptional isolation of the 903nm wavelength in high-stakes environments.

Unrivaled Optical Performance

Centered precisely at 903nm with an ultra-narrow bandwidth, the LTH903 filter achieves:

• Extreme Out-of-Band Rejection (OD 6+ typical across UV-VIS-NIR)

• Peak Transmission Efficiency (>90% typical in passband)

• Critical Signal Isolation for low-energy NIR/SWIR signals

• Noise Suppression for enhanced SNR in photon-starved applications

Engineered for Rigorous Use

Crafted with premium optical glass substrates and advanced thin-film interference coatings, the LTH903 guarantees:

• Thermal & Mechanical Stability – Minimal shift under temperature stress/vibration

• Hard-Coated Surfaces – Scratch-resistant, chemical-proof, and easy-clean

• Long-Term Reliability – Consistent performance in harsh industrial/lab settings

Ideal for systems requiring precise 903nm isolation:

• LIDAR & Rangefinding: Enhance target discrimination and reduce false returns

• Night Vision & Surveillance: Improve contrast in NIR imaging systems

• Fluorescence Analysis: Detect deep-tissue or quantum dot emissions

• Spectroscopy: Isolate absorption lines in gas analysis (e.g., moisture detection)

• Fiber Optic Communications: Filter noise in telecom wavelength-division multiplexing

• Industrial Sensing: Enable precision monitoring in process control and sorting
