Product Description
Laser Optic Lens:

OPTICAL ANTI-REFLECTION COATINGS

"Anti-reflective coating enhances performance!“

Each beam of light generates a back reflection during the transition from one into another medium. Antireflective coatings are used to minimize effects like loss of power and the appearance of dangerous hotspots caused by the back reflection.

Antireflective coatings (short AR-coating) are used in a variety in optics as they reduce the reflection of glass surfaces. The increased light transmission and a reduction of aberrations are the main advantages.


PRODUCT FEATURES

1. Single layer - AR (advantageous for materials with high refractive index)

2. Narrow-band AR coatings

(e.g. for V-type single laser wavelength).

3. Broadband AR coatings

4. Multispectral AR coatings

TYPICAL APPLICATIONS

1. Anti reflective sight glass window to protect

2. high-quality laser optics from splashing material

Anti reflective laser scanner window


PROTECTIVE WINDOWS FOR DISC-ND:YAG- AND FIBER-LASERS

Used as last optics to be placed before the working area to protect the high-class laser optics from material spilling during the laser welding and cutting process.


THE FOLLOWING SPECIFICATION IS NECESSARY FOR A QUOTATION:

1. Required wavelength range

2. Substrate material

(f. e. Fused Silica, BK7, Borosilicate glass 3.3, Float glass, Sapphire, Zn-Se and more)

1. Dimensions.

2. Transmission output, Reflection

3. Angle of incidence in degrees

4. Laser power density in W/cm² (CW)

Energy density in J/cm² (pulsed laser).


SAMPLE CURVES FOR A COATED FUSED SILICA SUBSTRATE FOR 1064NM, 1030-1090NM, ND:YAG LASER

TRANSMISSION MEASUREMENTS

Our spectral transmission tests are made in-House.

COATING RANGE

All AR-Coating scan be offered with a wavelength range between 200-3000nm. Due to different coating materials and designs were able to influence the broad band.
