Reflective Condenser
-
Reflective condensing system and focusing accessory for coupling light sources to monochromators. It uses two mirrors to focus to the entrance slit. The reflective system eliminates chromatic aberration, provides maximum spectral range, and does not require refocusing. Accessories like light choppers and filter wheels can also fit inside next to the slit. Versions with rotatable mirror available for up to four source direction.

Optical Chopper
-
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.

Light Sources

There are many low cost artificial light sources used for illumination or for industrial applications: tungsten or halogen bulbs, fluorescent lamps, LED lamps etc. Some of these sources have regulated intensity of emitted light. However, there very few calibrated light sources of precisely known parameters. A light source can be considered as calibrated when its user can precisely regulate its photometric/radiometric parameters like luminance (or illuminance), radiance (or irradiance) at defined spectrum of interest. Such light sources are needed in many applications among them, in systems for testing night vision devices, VIS-NIR cameras and SWIR imagers. Inframet offers a series of calibrated light sources that can be divides into three groups:

Light Simulator
-
From the review of the scientific development history, reliable and stable artificial light sources have played a very important role in the past century. For example, the artificial solar simulator is an important part of simulating sunlight to ensure accurate performance of PV characterization. With the growth of light sensor applications, more and more requirement of light simulators (or artificial light sources) explored. One of the core technologies of Enlitech is the artificial light sources. We can manipulate different lamp types (short arc lamps, LEDs, filament lamps et. al.) to generate different spectrum-form in different light intensity levels, beam sizes, and wavelength ranges. We have launched different artificial light source products for different applications fields. For instance, SS-X series solar simulators and ILS-30 ambient light simulator are for the PV field, HAAS is highly accurate star light simulator for the space field, and ALS-300 is a general-purpose light source in science research field. These products can not only meet the needs of your application, but also speed up the process of your research or mass-production.

Light Meters
-
Light Meters are used to measure the light output of an illumination source for a number of optical applications. Light Meters are measurement devices that feature photodiodes to determine the level of light transmitted from a source. Light Meters possess simple, easy to read screens upon which measurements are displayed in one or more photometric units. Most Light Meters possess traceable NIST certification for proof of accuracy.
