UV Laser Optics
Overview
As OPTOMAN is playing a protagonist role for laser system developers, the beam delivery setup in machines designed for micro drilling, micro structuring, micro shaping, and laser processing in general, motivated OPTOMAN to optimize Ion Beam Sputtering coatings for laser processing applications.
Key Problems
OPTOMAN has fought many battles. From the experience gathered throughout these years, he highlighted main problems laser processing faces.
Short duty cycle and lifetime of machines caused by coating absorption and laser damage.
Beam profile deformation.
Polarization sensitivity requires beam delivery components to be optimized for s and p at the same time.
Multiple wavelengths coverage in the system.
What can OPTOMAN do for the laser processing market?
Lower cost of ownership due to enhanced lifetime.
OPTOMAN’s concentration on high LIDT and enhanced lifetime IBS coatings allows industrial players to forget about headaches when components have to be replaced after a short period of time. Learn more about this here.
Laser optics made by OPTOMAN, due to low absorption, low surface roughness and high batch-to-batch repeatability, offer higher longevity than optics produced by others, thus lowering the Total Cost of Ownership and ensuring the cost of supply wouldn’t be just the tip of the iceberg when purchasing optics.
Ultraviolet Laser Optics for Laser Processing applications
Inspired by the challenges that industrial players in the micromachining market face, OPTOMAN has done quite a unique thing – optimized the IBS coating process to make low absorption and high longevity dielectric optical components for ULTRA VIOLE[n]T LASERS.
UV optics face quite a share of challenges, however, the main ones are:
- Low transparency due to low absorption.
- Scattering due to even tiny imperfections.
- Laser damage and long-term degradation.
OPTOMAN solves these challenges by making them scatter-free and lowering the absorption to as little as possible, which results in increased longevity of optics. Sounds easy, right? Trust us when we say it - it is not. We've put a lot of time and resources into several R&D runs to develop the ideal product for laser processing.
Custom - Custom shape, curvature and size.
- Spectral range 193 nm - 5000 nm.
- Size range from 3 mm up to 360 mm.
- Optimization for 2, 3, 4 or more wavelengths.
- Various angles of incidence.
And what about LIDT?
Laser damage is the arch-enemy of UV optics.
To fight it, one must measure it.
So OPTOMAN does.
If you're using an Ultrafast Laser...
OPTOMAN has you covered as well.
Newest addition to the UV product portfolio
OPTOMAN lifts the spectrum! This time at 193 nm lifting it way above market average - beating R>98%, AOI = 45 ° threshold and doing it repeatable!
IBS dielectric coatings advantages for ArF lasers compared to other solutions in the market:
- No Aging (reflectance does not change over time)
- Longer lifetime
- Low loss and absorption
- Higher LIDT
HR > 98% @ 193nm, AOI=0-10° spherical mirrors are also available as well as custom size and wavelengths.
