Intracavity Mirror Coating

Ophir Optronics Ltd. has announced that the CO2 Laser Optics Div. of its Optics Group has developed an MMR-P intracavity mirror coating for use in high-power CO2 laser systems based on multimirror-cavity optics. The company says that the coating maximizes reflection (>99.90% for S-Pol), improves performance, protects highly sensitive mirror surfaces and prolongs product life. The OEM-approved coating provides good P reflection (>99.80%) and total random reflection (>99.85%) and is suitable for Cu and Si mirrors. It is ultraviolet-resistant and allows for a phase-shift tolerance of ±2 at 45° and >70% reflection for 630 to 670 nm, for good cutting and cleaning capabilities. It can be used as a total reflector or as a zero-phase-shift total reflector and can be applied to a level-changing mirror in two-tiered resonator systems.

Coated Lens

Clear Magic is an ultra-low-absorption lens with a coating transparent to visible light. The coating allows beams from helium-neon lasers to be seen on the workpiece, while polarizing filters help to detect thermally induced stress.
It is available in 1.5 and 2 in. diameters for most popular OEM systems.

Seeing Clearly

There are three important features every laser system's lens should have: longevity, an easy-to-clean coating for durability and low heat absorption.

But few lens manufacturers have lenses that offer all three. When laser start approaching power levels of 4 kW and higher, a lens' low heat absorption is critical to its lifespan. Thermally induced stress from the heat can crack or even shatter the lens.

Ultra-low-absorption lens

Ophir Optronics Ltd. (Jerusalem, Israel; www.ophiropt.com) CO2 Optics Group has developed an ultra-low absorption lens called Clear Magic, as a complement to its Black Magic lens. Clear Magic features the same unique characteristics of its Black Magic counterpart while providing the benefits of a coating transparent to visible light. The new lens uses the same top layer as Black Magic, which offers superior cleaning properties and scratch resistance. Its transparent coating allows HeNe beams to be seen on the workpiece, while polarizing filters help to detect thermally induced stress. Clear Magic is available in 1.5 and 2 in. diameters for most popular OEM systems.

It’s a kind of magic
The constantly increasing outputs of laser-cutting systems pose a real challenge on the lenses, because in the case of high-output laser beams, a rather low absorption rate is required in order to maintain full and constant process control. Lens makers like Ophir Optronics took on the challenge and have developed lenses that are not only able to cope with the highest available laser outputs, but also have a higher lifespan in comparison with their predecessors, despite the higher outputs.

New Optics Package
Ophir Optronics recently unveiled the EZ-Pack, what the company is calling the most advanced form of packaging for industrial laser optics.

Composed of Polyethylene Terephthalate (PET), a recyclable plastic widely used in the beverage industry, EZ-Pack is both environmentally-friendly and durable. Due to EZ-Pack design, the lens practically 'floats' within its enclosure, eliminating tha need for wrapping paper and a plastic bag. Because no material comes in contact with the optical surfaces, there is no dirt or loose fibers to contend with and no cleaning is required prior to mounting. Every unit is vacuum-sealed to prevent humidity and extend the lens' shelf-life.

The lens practically “floats” within its enclosure, eliminating the need for wrapping paper and a plastic bag. Because no material comes in contact with the optical surfaces, there is no potential dirt or loose fibers to contend with, and no cleaning is required prior to mounting. Every unit is vacuum-sealed to prevent humidity and extend the lens’ shelf-life. EZ-Pack is now available for standard 1.5-in. dia. laser lenses. Future versions of the product are being planned for other lenses and mirrors sizes.

"It's magic: Two consumables that are very important when running a laser are the focusing lens and gases used for cutting. …Ophir's new Black Magic focusing lens gives long life. It averages about 600 hours of use compared to roughly 300 hours to 400 hours with ordinary yellow lenses. A high-power laser puts more demand on critical components, such as mirrors and lenses, resulting in higher lens-replacement costs. The black Magic lens has less absorption of the laser beam than standard lenses, especially important with today's high-wattage lasers. This keeps power at the focal point for cutting, not in heating the lens. Black Magic lenses are made from the highest grade of low-absorption zinc selenide, and its proprietary coating is less sensitive to the heating effects of the laser beam. As a result, the usual thermal response of a lens during use, causing the focal length to move, isn't an issue. The focal length of the black magic lens stays constant."

Thanks to Ophir Optics, in June I had the opportunity to visit Jerusalem where the company's main manufacturing plant is located. Ophir makes the vital lenses and mirrors needed by lasers to focus the light beam and to transit the light. Seeing what it takes to produce a lens was quite fascinating. Ophir starts with a raw piece of zinc selenide, grinds it or turns it to the needed specifications and then coats it with various substances to provide enhanced performance and scratch protection.
