How to Choose Integrating Sphere


Integrating Sphere system fulfills two important parts; one for measuring and analysis and other is the assistant part that provides testing environmental. While choosing an integrating sphere always consider the size of the lamp, type of lamp and the reflectance material used in the sphere. Most of the integrating sphere comes with some additional interchangeable features for the light source, assemblies, and post reducers. This makes it perfect for the use of various applications.

Integrating sphere from Labsphere is perfectly designed having a port frame, easy access mounting options, and quick change accessory options. This design meets your maximum requirements.

Size of the integrating sphere: The diameter of the integrating sphere ranges from several centimeters to several meters. The lighting industry uses the integrating sphere of the size from 0.3 m to 4 m. The sphere of size 0.3m to 0.5 m is used to test single LED whole of size 1 m is used to test LED bulb, CFL lamps, and flashlight. The one with the size between 1.5 m to 4 m is suitable for all kind of lamps.

Testing Ways of Labsphere’s Integrating Sphere: Usually the test method of integrating sphere uses two methods, one is a center test or 4π test and the second is side opening test or 2π test. The most commonly used test method is a 4π method that is suitable to test SSL products like a LED bulb, CFL, HID etc and 2π is used for a LED street lamp, LED panel etc.

Labsphere’s integrating sphere can be customized and you can create your own uniform source or light measurement system or can modify the existing system within minutes.

The spheres are offered with Spectraflect, Spectralon and Infragold coating that combines with the highly reflective surface with neat and perfect Lambertian reflectance. These coatings over the surface make it more durable and stable over time and ensure optimal integration of light over the lifetime of your sphere.

The Labsphere’s integrating sphere is certified and registered and once you find your desired product you can take help of qualified engineers to use it to meet your application needs.

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
