How much does an integrating sphere cost?

Optical radiation is measured using the integrating spheres, which is the most popular and frequently used instrument for this purpose. It is intended to produce a uniform distribution of optical radiation at the sphere’s inner surface via the use of numerous Lambertian reflections at the sphere’s inner surface. It is possible to utilize the integrating sphere to measure the radiant power and total luminous flux produced by a light source by acting as the input optical element for a detector of radiant power, which is positioned at its exit port, while the integrating is a sphere is being used for this purpose. Light sources may be placed in front of or within the sphere, depending on the kind of emission they emit. 

LED measurement
Since there has been an increase in the development and manufacturing of LED tube lights, there has also been an increase in the need for testing techniques that are particularly suited to these lights. Because of their enormous size, typical LED tube lights range in length from two to four feet in length, requiring specific instrument designs to suit their use.

LED manufacturers do quality assurance testing on their lights throughout the original research and development phase as well as throughout the manufacturing process to ensure that their products are of the highest possible quality. Manufacturers are mainly concerned with measuring the brightness of the lamps, the colour of the light they generate, and the efficiency of the lights they produce, among other things.

Price range
An integrating sphere is generally available for purchase for a price starting at 6000 US dollars. Furthermore, if you want one of the finest integrating spheres, it will cost you about 10000 US dollars as well. LISUN also provides the best integrating sphere at a reasonable price.

Applications of integrating sphere
When it comes to LED testing, integrating spheres are the most often utilised kind of optical collecting device. When used in conjunction with a spectroradiometer, power supply, and light measurement software, integrating spheres excel in uniform light collection, enabling applications such as measuring the total energy output and colorimetric characteristics of LED lights and luminaries.

To put it in the simplest words possible, an integrating sphere is made up of a spherical shell with an optical coating on its inner surface that is diffuse white and highly reflecting. Light is admitted or released via ports or holes in the spherical wall, where it is subjected to numerous diffuse reflections inside the sphere hollow. This kind of reflection helps to spatially homogenize the light traveling through the sphere, resulting in a substantial attenuation of the optical signal in the process. Baffles are often placed strategically inside the spherical cavity to protect system components from unwanted direct light, thus improving sphere performance and reducing costs.

With relatively low uncertainty, integrating sphere systems offer an effective method of measuring the total brightness flux and correlated colour temperature (CCT) of LED tube lights. Setup and measurement durations are both very short, allowing for high throughput to be maintained. Integrating spheres systems are also used in the calculation of luminous efficacy and the determination of the efficiency of LED lights.
