Select A Collimating Lens For Your Laser DiodeFor example, the NA of the A390-B or A390TM-B is 0.53, which is more than twice the approximation of the NA of a laser diode (0.26) so it can be used for this laser diode. Note that the focal length of these lenses is 4.6 mm, so the collimated long axis beam diameter is about 2.5 mm.
Four collimating lenses are designed for a variety of visible and near-IR diode-laser applications. Each lens has a focal length of 5 mm, a numerical aperture of 0.5, and an image-field diameter of 0.14 mm. The three-element lenses are corrected to work with diode-laser windows 0.3 mm thick. All air-to-glass surfaces are coated to provide more than 95% transmission at wavelengths between 514 ...

A = 1 = Laser diode collimator with 1.3" diameter flange. 3 = Laser diode collimator with 0.79" diameter flange. 4 = Laser diode collimator with 0.59" diameter flange. 5 = 10mm diameter single piece laser diode collimator. P = is the laser diode power in mW (e.g. 5LD for 5mW laser diode). f = is the focal length of the collimating lens, in
The most simple and popular way is to collimate a laser diode beam by using a single aspheric lens. (see Fig. 1). The larger is the focal length of this lens, the larger will the beam diameter be after collimation. Furthermore, if a certain beam adjustment has to be made, for example in order to expand the beam radius of a collimated beam, two ...
If left as new you can make a diffraction limited reference beam with no spatial filter by simply removing the collimating lens. Cleaning the window is very challenging. Some other tips: The diode is very fragile. Don't bend the pins, subject the diode to shock or static electricity.
Collimated laser diodes are an assembly of a laser diode with a specified collimating lens within a small package. World Star Tech offers collimated laser diodes from 400nm to 1064nm with a standard or custom design. Our experienced design team will offer custom laser diode collimators with desired divergence and beam size and shape.
Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. It consists of a laser diode holder, a collimating lens holder, and a high numerical aperture (NA) collimating lens, with a focal length f. The lens is housed in a threaded receptacle that is screwed into the collimating lens holder.
The focal lens acts like a magnifying glass and sunlight. For a 55mm lens, the laser beam passes through the lens and converges to the smallest point at about 55mm from the edge of the lens. The laser beam is concentrated to the smallest size at this "spot". Fig. 1. Aspheric lens is being used to collimate a laser diode beam.
The operating temperature for the lenses ranges from 0 to +65 °C. The CAW100 is a plastic lens of 785 nm with a numerical aperture of 0.195. It is mainly used as a collimator for diode lasers and will replace the lens type CAX100. The focal distance at the specified wavelength of 785 nm is 9.85 nm and the diameter is 5.2 mm.

Diode-laser collimating lenses Four collimating lenses are designed for a variety of visible and near-IR diode-laser applications.

One lens with a negative focal length and the other with a positive one creates a setup to collimate and expand or shrink the beam. Quite frequently the most popular way to focus a laser diode beam is to use a two lens system where one lens collimates the highly divergent beam and the second lens focusses it.

2020-03-14. What restrictions apply to how long the light from an extended, non-laser source like a tungsten lamp can stay collimated? Answer from the author:. You can estimate that with the beam parameter product, using the source size (like a beam waist) and the divergence of outgoing light (light a beam divergence).
The design of a new collimating lens system for a laser diode package for optical communication is discussed. This collimating lens system achieves enough space between the laser chip and the lens, with the beam diameter smaller than the effective diameter of the isolator. This system consists of two lenses. For beam angle deviations caused by misalignments of the laser diode and the lens ...
