Achromatic Lenses
JML Optical Industries
Achromatic doublets and triplets are compound lenses composed of two and three singlets. Designers often abbreviate their reference to achromatic doublets and triplets by simply calling them achromats.
The origin of the technical term "achromatic" is in the colour-corrected performance of compound lenses. They are designed to outperform singlets by all measures, but designers give special attention to the reduction of colour effects in their images. "Achromatic" literally means "without colour," and in lens design, the term refers to minimal difference of focal length between two specific wavelengths.

F-Theta Scan Lens
Wavelength Technology
F-Theta scan lens rugged single and double elements are designed for Nd:YAG, Green, UV laser system that employ X - Y galvo scanning mirrors.
SL Serie Nd:YAG, Green & UV Laser
The lens are widely used in fields such as engraving and marking applications.
Telecentric Scan Lens- Visible
Wavelength Technology
Telecentric scanning lenses are a special configuration in which the arrangement of optics is designed to focus down the beam such that it is
always perpendicular to the flat field.
TSL Serie
This is accomplished by ensuring that the system 'stop' is located at the front focal point of the
lens system. The 'stop' is located at the position where the beam is deflected from the axis. In a single-axis scanning system, this location
is at the scanning mirror. For two-axis scanning, the stop is mid-way between the mirrors.
