Precision is king

In the optical path of a LiDAR system, precision of the interacting components is a must. It is crucial that the laser beam doesn’t suffer a loss of quality or performance. 

Up against a challenge? SCHOTT is an expert and masters the entire value chain from raw glass to aspherical coated lenses.

BOROFLOAT ® 33

Unique in total

BOROFLOAT ®33 significantly increases transparency for colorless visual appearance, provides a low refractive index as well as a low coefficient of linear thermal expansion. Thus, it is the ideal substrate for narrow bandpass filters. Moreover, it attends with very good temperature stability and excellent resistance to thermal shock. It is why BOROFLOAT®33 glass is also additionally a robust substrate for LiDAR mirrors and beamsplitters. It stands out with its mirror-like surface and superior flatness.
Thin glass D263® T eco

Pristine surface

Due to high precision and accuracy of a proprietary down draw process, D263® T eco glass provides a pristine surface without the need for polishing. D263® T eco glass can be manufactured down to 30 micrometer.

RG80 optical filter glass

More sensitivity

Narrow band-pass interference filters used in LiDAR sensors isolate and transmit the return signal while attenuating over a large wavelength range sunlight and ambient light. RG80 blocks out the visible light to improve the sensitivity of LIDAR systems. Performance can be further enhanced when combined with a bandpass design.

 
MEMpax®

Perfect for reflective coatings

The outstanding properties of MEMpax® allow for an excellent coating substrate with low total thickness variation (TTV) to fulfil MEMS mirror requirements. No polishing is needed. It matches with silicon in terms of its thermal expansion, and is also well suited for anodic bonding. Due to its properties, MEMpax® serves as an ideal substrate for reflective coatings.

Optical Glass

Optimized reliability

LiDAR sensors must deliver long lasting good image quality regardless of temperature differences or aggressive climate conditions. SCHOTT optical glass offers optimized reliability and performances by enabling thermalized lens systems for LiDAR sensors.
Aspherical lenses

Image quality guaranteed

Aspherical lenses are increasingly used to replace multi-spherical element assemblies in LiDAR lens systems. SCHOTT offers aspherical lenses made using MRF technology in various sizes and materials. The result: weight reduction, a compact design and superior overall image quality.
