Durable and reliable optical components for industrial sensing, LiDAR, laser rangefinding, and photoelectric detection — engineered to perform in demanding environments.
Industrial sensing, laser rangefinding, and photoelectric detection systems require durable, reliable optical components that maintain performance under harsh operating conditions. Key challenges include:
Automotive grade: -40°C to +105°C. Industrial grade: -20°C to +70°C. Thermal stability of optical performance is critical.
Components must survive mechanical shock (50g+) and continuous vibration without optical alignment shift or coating delamination.
Bandpass filter center wavelength tolerance ±2 nm for LiDAR; AR coating performance matched to specific laser diode wavelength.
Laser sensor windows must handle continuous-wave or pulsed laser power without thermal damage or coating degradation.
IP67/IP69K rated protection for outdoor and washdown applications. Optical windows serve as the sealing barrier.
10+ years without performance degradation. Coating adhesion and substrate stability validated through accelerated aging tests.
350 nm – 2 μm
Standard material for visible and NIR industrial sensors. Cost-effective, good optical quality, widely available.
180 nm – 2.1 μm
For applications requiring superior thermal shock resistance and UV transmission. Low thermal expansion for dimensionally stable optics.
0.5 μm – 20 μm
Standard window material for thermal imaging systems (8-14 μm LWIR band). Essential for infrared temperature sensing and thermal cameras.
2 – 14 μm
High refractive index (n=4.0) makes it ideal for LWIR lens elements. Requires AR coating on both surfaces due to ~36% uncoated reflection.

Coating selection depends on wavelength, power level and application environment. Common options for this application:
Broadband anti-reflection coatings for visible and NIR industrial imaging systems. Reduces ghost reflections and increases throughput in inspection and measurement applications.
High-reflectance dielectric coatings for laser processing mirrors and beam delivery systems used in industrial cutting, welding and marking.
Durable overcoats for optics operating in harsh industrial environments — resistance to abrasion, coolant mist, cleaning agents and temperature cycling.
Anti-reflection and filter coatings for near-infrared and short-wave IR industrial inspection systems. Enables wavelength-specific contrast enhancement.
Wavelength-specific AR coatings matched to laser diode emission (850 nm, 905 nm, 1550 nm). Reduces back-reflection into laser source and increases signal throughput.
Dielectric HR mirrors for beam steering in LiDAR scanners. >99.5% reflectivity at target wavelength with low absorption.
Narrow bandpass filters for ambient light rejection in optical sensors. Blocks sunlight and artificial lighting while passing signal wavelength.

Optical coatings must maintain adhesion and spectral performance after years of thermal cycling, humidity exposure, and mechanical vibration. Accelerated life testing per Telcordia GR-1221 or IEC 60068 is often required.
Automotive LiDAR programs may require 100K+ units per year. Every unit must meet the same optical and mechanical specification — demanding reliable process control and SPC.
Industrial applications demand optical quality at consumer-electronics pricing. This requires optimized manufacturing processes and supply chain management to achieve target cost points.
