Importance of Collimating Lens


The collimator is a device that changes the diverging light or other radiations from a point source into a parallel beam. This specific feature of the device makes it an important part in spectroscopy and geometric and physical optics.

An optical collimator consists of a tube with a convex lens at one end and an adjustable aperture at the other. The collimating lens of Thorlabs inside the collimator produces rays into the parallel beam so that the image can be viewed without parallax.

Uses of Collimating Lens

The collimating lens of Thorlabs or other labs is curved optical lenses that are used by the user to control the field of view, collection efficiency and spatial resolution of their setups. It is also used to configure illumination and collection angles for sampling.

Use of Collimating Lenses in Radiology

The collimator lens is also used in radiology where a collimator is an arrangement of absorbers for limiting beam of X-rays, gamma rays, or nuclear particles to the dimensions and angular spread required for the specific application.

Use of Collimating Lenses in Spectroscopy Setups

Collimating Lens is used in free space optics. Free space optics collect the light energy from open beams and surfaces and directs it towards the spectrometer or can be attached to the optical fiber or integrated with sampling accessories.

Adjustment of Focus of Collimating Lens

To carry out some work, the focus of the collimating lens should be adjusted in such a way that the collimated light when enter the sample get transmitted to the optical device at the other end. A collimating lens in Thorlabs is available at a different wavelength range and focal length. You can select the one from the different options available as per your requirement.

Everything You Want to know About Collimating Lens from Thorlabs or Elsewhere

Image
Collimating lenses are optical lenses that help in making the light entering into the spectrophotometer parallel. With a collimating lens from Thorlabs or elsewhere, one can control the field of view, spatial resolution of their setup, collection angles for sampling and illumination. Why are they important in the first place? One of the prime reasons for use of the collimating lens is high divergence result of a laser diode. It is made up of aspheric lenses, they do not pose spherical aberration. Collimating lenses are usually picked as and when a collimated beam requirement is between one and five millimetres. Where are they used and how are they used? Collimating lens is placed inside a collimator. An Optical collimator is utilized for calibration, testing and measurement. In one of the types of the collimator, patterns are projected into infinity. When a target is kept in the focal plane of a collimator, the uniform target seems extremely near. This phe

Collimating Lens from Throlabs for LED

Image
LED has a small protective dome over the diode that is commonly known as the primary optic that serves to protect and shape the output of the small diode. But light from the primary optic of the LED is broad for most application and lacks intensity for long distance. To reduce this drawback LED fixtures use secondary fixtures like collimating lens from Thorlabs or other labs, reflectors, TIR optics etc that collects light and magnifies its intensity towards the target. If you wish to create lenses and reflectors for LEDs, then you need to use some logical ways apart from just scaling them down from the light source. This is because LED has much smaller form factors than other light sources and also differs in the way it emits light . Use of collimating lens in LED          The collimating lens of the LED undergoes the process of Total Internal Reflection or TIR. TIR is defined as the complete reflection of a ray of light within a medium such as water or glass from the
