Lobre Products: Optical Polarisers
Optical polarisers, also known as waveplates, are components used to manipulate the polarisation state of light.
Lobre offers custom manufacturing of both standard and thin-film polarisers (produced using high-vacuum deposition technology), available in linear and circular geometries. Depending on the application requirements, these optical components can control the direction and type of polarisation (linear, circular or elliptical).

High-precision optical polarisers for advanced systems
Half-wave and quarter-wave plates are among the most commonly used solutions; however, Lobre leverages 80 years of experience to design and manufacture high-performance custom optical polarisers.
We support our clients step by step for small batches or large-scale production, also applying polarising surface treatments on one side and multi-layer anti-reflection coatings on the other, ensuring optimal transmission and high contrast.
Half-Wave Plate
Half-wave plates are optical components used to modulate and rotate the direction of linearly polarised light.
Quarter-Wave Plate
Quarter-wave plates convert linearly polarised beams into circularly polarised beams and vice versa.
Custom Waveplate
We manufacture high-precision optical polarisers with customised shape, thickness and surface coating.

Space||Aerospace||Vision Systems||I.T.S.||Biomedical||Security||Laser||Lighting
Space and Aerospace
Polarisers for imaging systems are crucial in remote sensing instruments aboard satellites and for their calibration.
Vision Systems
Polarisers for industrial optical analysis deliver sharper images by increasing contrast and reducing stray reflections.
Speed Detection - I.T.S.
They enable precise reading of visual data in intelligent transportation systems by selecting polarised beams.
Biomedical
Polarisers for scientific applications in the medical field are essential for microscopy and non‑invasive diagnostic techniques.
Security
Polarisers for industrial cameras are used in systems to detect people using selective polarisation.
Laser
They allow control of polarisation in high-power laser systems, improving beam quality and performance.
Lighting
In advanced optical lighting systems, polarisers ensure uniform emission and reduce unwanted glare.
Optical polarisers, such as polarising filters or polarised beam splitters, are versatile components used in many applications. Primary areas include the aerospace and space sectors, biomedical instruments, industrial vision systems, traffic control and lighting systems.
Depending on the thickness of the crystal, the behaviour of waveplates changes, making optical components more or less suitable for specific contexts. For example, polarisers used to suppress reflections can enhance image quality and efficiently analyse light polarisation in photography, industrial processes and laboratory environments.
