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, ...

Light sources are needed for transmission, absorption and reflection spectroscopic setups. To couple, the light conveniently with the fiber optic bundles, bundles and probes it is essential to collect the light and couple it through SMA-905 connectors. There are different light sources like Tungsten-Halogen light source, Deuterium-Halogen Light Source , LED, Mercury-Argon etc that have different application and wavelength ranges. Tungsten-halogen light source provides stable output and is used in the visible range to do color measurements. Halogen light provides stable output and its life depends on the color and temperature of the bulb. The high stability of halogen light source makes it suitable for the use as a color reflection illumination source and as an irradiance calibration light source. Deuterium light source is found in combination with halogen and is called Deuterium-Halogen Light Source . It provides a stable output and is used in UV-absorption or reflection...

Different types of parabolic, spherical, and flat mirrors are produced having different types of mirror substrates . These products have a variety of metallic and dielectric coatings that make them suitable for various applications. The various types of mirror coatings include Protected Aluminum, Enhanced Aluminum, UV Enhanced Aluminum, Bare Gold, and Protected Gold etc that are used for visible applications. UV and DUV enhanced aluminum is used for UV and visible applications while Bare and Protected Gold offer high reflectance for near Infrared and Infrared Wavelength. First Surface and Second Surface Mirrors All the mirrors you use are first surface mirrors. This mirror has a high reflectance coating deposited on the front surface of a variety of different types of glass, metal or semiconductor substrates. The other surface of the mirror may be clear or ground and the mirror is oriented so that the coating faces the source. They are widely used in precision optics ap...

Halogen has been used as the light source for decades and is chosen as the source of illumination for varieties of imaging modalities. But now LEDs is gaining popularity in the marketplace and increasingly becoming a preferred choice for a light source in various optical instruments due to its many advantages. Before comparing the characteristics of both light source, have a look on the how halogen and LED lamps produces light. Halogen Lights Halogen light source is similar to incandescent bulbs. It consists of tungsten filament surrounded by quartz envelope filled with an inert gas that makes it preferable for the use in a microscope for bright field and phase contrast microscope. With the supply of electricity, tungsten begins to glow just as within the incandescent bulb. As tungsten glows it begins to evaporate, giving off tungsten atoms. This lowers the brightness of the lamp with time. The gas present inside the lamp reacts with the tungsten vapors and recoats it...

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 ...

An ultraviolet-visible spectrophotometer can measure the wavelength of light near UV and near Infrared range i.e. from 190 nm to 1100 nm. It is used in the quantitative determination of concentrations of the absorber in the solutions of transition metal ions and highly conjugated organic compounds. The UV/VIS spectrophotometer has a different specific sample cell (sample chamber), and cuvette (sample tube) and also have different types of light sources. The different light sources that are used in spectrophotometer are deuterium light source, halogen light source, deuterium-halogen light source , xenon light source, tungsten light source. Today the spectrophotometer comes with different light sources that change its wavelength automatically for optimized and interruption-free operation. The choice of a light source in the spectrophotometer depends on various factors. The desirable features for light sources are: •     Uniform light output over a specified w...
