MSE PRO™ Assembly Air-Spaced Focusing Laser Lenses

MSE supplies offers Assembly Air-Spaced Focusing Laser Lenses. These lenses are designed to focus the high-power radiation emitted by lasers. These lenses are specifically designed for precise tasks, making them ideal for laser machining systems used in welding, cutting, drilling, and strutting applications. These lenses are also suitable for collimating fiber-delivered laser beams. The MSE PRO™ air-spaced focusing lens product utilizes high quality triple lens elements which are optimized to obtain a diffraction-limited focus spot. With the design-specific optical coating, the lens system achieves transmission throughout at a designed wavelength up to 98%. 

The minimal possible focus spot size from an air-spaced focusing lens is calculated by the wavelength of the laser multiplied with the focal length of the lens, f', the FAP factor and the diffraction value M2 of the laser beam, and divided by the diameter beam(1/e2).

The depth of focus of an air-spaced focusing lens is defined by a doubled Rayleigh length. The Rayleigh length describes as a distance, along the optical axis, between the positions where the beam area is doubled in front of or behind the focal position.
The Rayleigh length ZR is calculated by the beam area in the focal plane multiplied with a factor (depending on the FAP-factor) divided by the wavelength and the diffraction value M2 of the laser.

MSE Supplies can offer a variety of optical components. Please contact us for customization or bulk orders.
