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, ...

General Description of Light Sources

Image
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...

Selecting the Right Collimating Lens from Thorlabs

Image
Lenses come with many aberrations like chromatic aberration and spherical aberration. To reduce aberrations and to increase the performance of your system it is important to choose a lens with a right design and correct multi-element systems. Thorlabs provides a high-quality optical material with the substrate and anti-reflection coating of a different wavelength. Spherical Singlets It is a preferable choice for many applications where aberration is not a great concern. The various singlet design of collimating lens Thorlabs are Plano-Convex, Bi-Convex, Plano-Concave, and Bi-Concave. These lenses are used for the wide application. Plano-Convex Lenses These lenses are used where the object or image distance is more than five times the other. Plano-convex lens of the Thorlabs performs best for collimating a point source or for focusing collimated light. These lenses are subjected to some aberration that reduces a multi-element system. Bi-Convex Lenses It...

Use of Ball Lenses for Coupling and Collimation

Image
Ball lenses are an optical component used for improving coupling between fibers, emitters, and detectors and for coupling and collimating in the range of 0.5 to 5mm in diameter. They are also used in endoscopy, barcode scanning, and sensor applications. Ball lens of Thorlabs are prepared using a single substrate of glass and is used for collimating light. The collimation of light depends on the geometry of input sources. The most important factor that is used to determine the performance of the ball lens is the numerical aperture. This is because of the spherical aberration of the ball lens in proportion to the cube of numerical aperture. This limits the use of ball lens for the use with fibers having a numerical aperture of 0.2 or less. Following parameters are used to defines the application of ball lens: •          The diameter of the input source •          The diameter of the b...

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 Biological Microscope

Image
A biological microscope is an optical microscope that is used to study microscopic organisms, cells, tissues and their vital processes. The magnification range of the microscope varies and depends on the objective lens attached to it. The objective lens is available in the range from 10x to 1000x. Some specialized version of biological microscopes is capable of performing fluorescence imaging and is commonly known as fluorescence microscopes. Kewlab deals in different types of the biological microscope and avails the product at an affordable price. Types of Biological Microscopes There are different types of biological microscope like a compound microscope, inverted microscope, and fluorescent microscope. These microscopes are used for different purpose and in different applications. Compound Microscope: A compound microscope is an extension of the magnifying glass that uses two or more lenses to produce the clear and enlarged image of an object. It magnifies an ...
