Lobre Products: Optical Windows
Optical windows are a type of flat, transparent optics featuring high-precision surfaces with irregularities down to λ/50 and parallelism < 1 arc second. These high-performance optical components are essential in industrial settings to protect sensors and optical systems.
Lobre has extensive experience in the production of free-form optical windows, where the contours can be manufactured with complex geometries, including custom steps and angles.
Optical windows for vision systems and thermal applications are specifically designed to shield sensors and devices from environmental exposure without compromising measurement accuracy.
Boasting 80 years of experience, Lobre supports clients in Italy and abroad across multiple sectors in the design and manufacturing of industrial optical windows with fully customised physical properties and surface treatments.
Feel free to contact us to request the design and production of custom optical windows for your optical systems and electronic sensors.
Key strengths of
optical windows
Since optical windows do not add power to an optical system, their value lies in their physical properties. For example, optical windows used in thermal applications must be able to withstand extreme temperatures repeatedly and over long periods.
Other key physical characteristics include: thermal resistance | scratch resistance | hardness | durability | shape | thickness | optical surface specifications (irregularity, parallelism, power, etc.).
Custom optical windows
We manufacture custom optical windows with personalised shapes, thicknesses, diameters, materials and coatings for any application.
Whether for small batches or series production, Lobre manages the entire process in-house, from design to the finished product, including optional surface treatments upon request.

Application Fields
Space||Aerospace||Vision Systems||I.T.S.||Biomedical||Security||Laser||Lighting
Space and Aerospace
Optical windows in the aerospace sector are used to protect optics and sensors from extreme thermal and mechanical shocks.
Vision Systems
Optical windows for vision systems are designed to be integrated into machinery used in workshops, factories and laboratories.
Speed Detection - I.T.S.
Optical windows for traffic monitoring and control ensure precision in all weather conditions.
Biomedical
Optical windows for scientific and biomedical devices must offer maximum protection for instruments such as surgical lasers and microscopes.
Security
Optical windows for security cameras and sensors must combine transparency and hardness to shield against external agents.
Laser
Industrial optical windows for laser applications must maintain high transmission and structural integrity even when exposed to high-energy sources.
Lighting
Optical windows for lighting systems are designed to maximise luminous efficiency and protect light sources from dust and environmental exposure.
Optical windows for industrial and scientific applications must meet strict optical and mechanical requirements.
For instance, optical windows used in scientific devices require precise transmission in the UV or IR spectrum, while in industrial environments, thermal resistance and surface durability are more important.
Thanks to the high precision of our machining processes, our experts can also manufacture free-form optical windows for specialised applications.
