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 par...

Fiber optics or optical fiber refers to the medium and the technology associated with the transmission of information as the light pulses along a glass or plastic strand or fiber. The central core to the fiber is surrounded by a cladding and a protective coating. Ones the light is injected into the core it remains trapped into it until emerged from the opposite end; this is because the cladding has a slightly higher index of refraction than the core. The sensors, illuminators, and toys make use of inexpensive plastic fibers. The environment that requires electrical isolation or protection from the elements uses fiber coupled LED . Coupling of Optical Fibers to LEDs and Sensors Although many fiber couplers are available for various LEDs and light sensors one can connect silica and plastic fibers directly to LEDs and sensors. Here are different methods used to produce fiber coupled LED and sensors. Preparing the Fiber Ends To obtain the best results use the plast...

Lenses come with many aberrations like chromatic aberration and spherical aberration. To reduce aberrations and to increase the performance of your system it is important to choose a lens with a right design and correct multi-element systems. Thorlabs provides a high-quality optical material with the substrate and anti-reflection coating of a different wavelength. Spherical Singlets It is a preferable choice for many applications where aberration is not a great concern. The various singlet design of collimating lens Thorlabs are Plano-Convex, Bi-Convex, Plano-Concave, and Bi-Concave. These lenses are used for the wide application. Plano-Convex Lenses These lenses are used where the object or image distance is more than five times the other. Plano-convex lens of the Thorlabs performs best for collimating a point source or for focusing collimated light. These lenses are subjected to some aberration that reduces a multi-element system. Bi-Convex Lenses It...

Integrating sphere is a versatile optical element that has multiple Lambertian reflections at the inner surface. This reflection results in the homogenous distribution of optical radiation. The radiation source located in two locations; either inside the sphere or in front of the source’s entrance port. Properties of integrating sphere The irradiance of the integrating sphere labsphere is proportional to the total radiant power emitted either by the source inside the sphere or by the one located at the entrance port. The irradiance level does not depend on the geometrical and directional distribution of the primary source if direct illumination of the respective location is prevented. This property makes the instrument useful optical element for the detection of radiant power. The radiance reflected from the inner surface of the sphere and shielded from the direct illumination, is constant in its directional distribution and independent of the specific location wher...

It is often required to transform light output from an optical fiber into a free-space collimated beam. Although to carry out this task, a simple collimation lens is sufficient, but it is necessary to fix the fiber end firmly at one end at the fixed distance from the lens. To fix the fiber at one end, fiber collimator is used. It is placed at the distance approximately equal to the focal length of the lens. Fiber Collimator is a passive device that combines the fiber and lens for collimating the light that is coming from the fiber, or for launching collimated light into the fiber. Features of Fiber Collimator ·          Fiber Collimator is made from a curved mirror or Collimating lens Thorlabs . ·          The light source in fiber collimator is placed at its focus that makes divergent light into a parallel beam or couple the parallel beam into the fiber. ·     ...

What is Calibration? Calibration is a process intimately associated with analytical balances. It determines the relationship between the displayed value and true mass by comparing their value with the known mass. It helps in determining the accuracy of an analytical balance or precision scale. Calibration is essential as it validates the precision of the weighing measurements. It also increases the longevity of the weighing scale and helps in producing valid data during rigorous testing. While shopping for calibration weight scale in the United States you come across the internal calibration and external calibration scale option. It is quite challenging to choose between two options. To make a smart decision you must have a complete knowledge of each type, the difference between them and their pros and cons. Read the following information and choose the calibration weight option in the United States smartly External Calibration External calibration is the...

Collimating is the process of aligning light or particles in a parallel fashion accurately. Collimating Lens Thorlabs Collimating lens Thorlabs is an optical lens that makes the passage of light parallel to each other when it passes through it. It helps the user to control the field of view, collection efficiency, and spatial resolution of the setup. It also helps in configuring illumination and to determine the angles for sampling. Uses of Collimating Lens ·          It is useful to measure the displays like color analysis, white point adjustment, flicker, response time gamma etc. ·          It can also be used in lighting measurement applications and is used to study the related parameters like spectral power distribution, color, and flicker. ·       It provides a stable and repeatable result as when it gets attached to spectrophotometer or other light s...

If you are biotechnologist, pharmacist or working in any other industry that requires working on scale, then before using it makes sure that it is calibrated to ensure correct measurement of your product. Calibration is the process of testing the scale and to ensure the level of accuracy as per your requirement.   If you are working in a laboratory, then measurement plays an important role in the outcome of your result. A wrong calibration could significantly affect your process. On the other hand, if you carry out a business that involves processing and manufacturing then a wrong measurement could change your product quality, scrapped batches, or even a product recall. Therefore, it is better to choose the best quality weighing balance for C alibration weight in the United States . Different Test to Perform While Calibrating Loads in Weighing Instruments You can check the calibration accuracy of weighing instrument by following the subsequent steps: •  ...
