Benefits of Fused Silica

Image
Fused Silica is the highly pure, non-crystalline material and is the most preferable choice for making mirror substrate, high performance lens, and simple stable tool. It has many benefits that make it a priority choice among the users. Some of the benefits of Fused Silica are: Range of Transmission: A fused silica produces the high throughput over a wide range of the spectrum. A standard UV fused silica transmits more than 90% in the wavelength range of 200nm to 2 microns with the least deviation at 1.4-micron wavelength. The IR grade fused silica achieves more than 90% transmission within the wavelength of 200 nm to 3.5 microns. Other fused silica varieties allow the transmission in the high-power semiconductor, extreme UV region of 248 nm and 193 nm due to the presence of some impurities.  Fused Silica is the most superior and versatile glass material as its transmission range lies within the limit of most of the optical glasses. Low Thermal Expansion ...

Different Types of Mirror Substrate

Image
A mirror substrate is the basic component of laser optics.   There are a few factors that determine the price and quality of mirror substrate like its material, a shape of substrate, size, tolerance and polishing quality. The good quality mirror substrate has following features: •          It should have flat and smooth surface. The flatness of mirror substrate is defined by the number of a wavelength of light that the surface can deviate from being the perfect plane. The number of the scratches and digs on substrate surface after polishing defines the smoothness of substrate. The best quality mirror substrate is the one that has a scratch specification of 20/10. •          It should be made of a material that is free of absorption for all wavelength of high transmission.     •          It should have high thermal conductivity. G...

Things you need to know about the Usage of Integrating Sphere Labsphere

Image
When one employs an integrating sphere labsphere for measuring optical power, you remove all the hassles faced with direct coupling method. But one must not forget that there are certain things about the integrating sphere you must know. Read on to learn about those things… You must pay attention to the internal reflectance The internal surface of the sphere should be highly reflective and at a wavelength of light which is to be measured. This only will ascertain the right measurements. Old integrating spheres were made up of two hollow hemispheres. The inner surface is usually given a coat of material which reflects wavelength of interest and eventually diffuses the input light. Coating used is sensitive to environment changes such as atmospheric conditions: bases, acids and vacuum). The integrating sphere labsphere must be coated every year. Calibrate detector and weight together  The distinct feature of any sphere and detector is completely specific to ...

Applications of Integrating Sphere Labsphere

Image
Integrating sphere is a device used to measure radiant flux. The flux is then carefully monitored either directly or when it comes in contact with a sample. One of the key applications of integrating sphere labsphere is measuring transmittance or reflectance through scattering or diffuse materials. There are more applications, learn about them below: Radiometer and photometer Integrating sphere labsphere when combined with a photodetector which is of the correct spectral response is utilized to calculate the gross geometric flux coming out of a light source. Flux density too of the illuminated areas can be calculated. It is the spectral properties of the light source which helps in deciding the right photodetection system. This is the first application. The Sphere Photometer By far the oldest of all the applications of integrating sphere is counting gross of geometric luminous flux from electric lamps. This method began towards the beginning of the 20 th...
