Know the Types of Calibration Weights in United States



How do you ensure that the scales used for certification by the weighing company for calibrating and certifying your weighing equipment are absolutely correct? The results are important for you, right? To ensure the results, some additional checks are needed so that no damage is made as regards the calibration error.  For instance, a bad fitting protective cover too can lead to weighing errors.

Know the types of calibration weights in United States here:

Cast Iron Bar & Hex Calibration Weights

Commonly used for testing commercial scales, industrial scales and retail scales. They are adjusted to MI tolerance equivalent to an accuracy of 1:20,000 or 0.005%.

These are called as bar weights and are available in 5g, 10g, 20g, and 25kg. Not good for the wet environment.

Brass Calibration Weights

Brass is less resistant to wear than iron, but more resistant to water. They are perfect for testing, weighing scales in food factories and other environments where the weights come in contact with water.

Brass calibration weights are available from 1g to 10kg.

Stainless Steel Calibration Weights

Wear-resistant and water-resistant, stainless steel weights are cylindrical and the best in the business. But they are difficult for carrying than iron weights.
Options – stainless steel M1 class calibration weights, Stainless steel F2 class calibration weights, Stainless steel F1 class calibration weights, and Stainless steel E2 class calibration weights. These types of calibration weights are the most stable of all in United States.

Miligram weights

Weights under 1g are milligram weights. These weights are made up of nickel sheet. To help you recognize the denomination, they are available in different shapes. A small lip is provided to help you pick them.

Slotted calibration weights

They are employed for testing crane gauges, force scales or suspended weighing scales. The hanger too is a weight and carries slotted weights. The latter are discs with slots.

Slotted calibration weights in United States are of either brass or iron; brass for smaller weights and hangers for testing weight up to 1000g with 4.5mm rod and slots.

Summing up
Pick the calibration weights that are most suitable for you depending on your requirement in United States.

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

Importance of Collimating Lens

Image
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
