GASIR® - optics for new and existing applications

07 Jul 2016

A unique molding process allows the manufacture of finished, spherical, aspherical and diffractive lens geometry in medium to large volume production runs with a competitive price-performance ratio. For low to medium volume needs GASIR^® can be manufactured with polishing or diamond turning.

Compared with germanium, the traditional infrared material, GASIR^® offers a wider transmission spectrum and much better possibilities to athermalize optics.

Umicore offers GASIR^® both as blank material lens or in off-the-shelf infrared lenses.

GASIR^®'s key advantages are:

• More stable pricing than germanium with the possibility for long term fix pricing
• Wider spectral range than germanium. GASIR^® is transparent from 0.8 µm up to 16 µm
• 8 times lower change of refractive index with temperature than germanium, allowing simple athermalized design
• Molding process allowing for high volume, cost effective optics

Potential application fields for GASIR^®  include:

• Automotive night vision and sensing
• Security and surveillance
• Thermography and predictive maintenance
• Fire fighting
• Smart sensing
• Defense
