Low Loss HR Mirrors
Low loss HR mirrors are essential in laser systems in which the lowest possible losses are required.
These mirrors are also referred to as IBS mirrors because of their ion-beam sputtering technology. Low loss HR mirrors provide maximum reflectance in a certain wavelength range and angles of incidence (AOI). Wide-angle (AOI 0-45°) mirrors are also available.
Metallic Coated Optics
Metallic coated optics are among the most fundamental types of mirrors used in the photonics market. With a very broad reflectivity range and low chromatic dispersion, they provide the perfect solution for numerous applications.
Plano-Convex Axicons
Plano-convex axicons (conical lenses) are used for a variety of applications.
Altechna offers two types of plano-convex axicons: regular and precision. Regular axicons create an annular beam in a far field, while precision-type axicons also transform a Gaussian beam into a non-diffractive Bessel beam in the near field.
S-waveplate
S-waveplate is a space-variant retarder that converts linear polarization to radial or azimuthal polarization. The product is unique for its high damage threshold, which exceeds that of alternative devices by 100 times. Unique results are achieved through the formation of subwavelength nanogratings inside fused silica glass. The enabling technology was developed
