The unique dual-output of equivalent beams make it a useful source for many comparative applications in addition to wavelength calibration and so on. The two output beams originate from two views of the single emitting spot where the electron beam from the single hairpin filament collides with the interchangeable anode.

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.

C+L Band Broadband Light Source
S-103
-
ASE broadband source slot module of FOTS system can offer special function that is able to change optical output spectral feature variously, which is change optical output spectral feature variously, which is followed by user’s driving embedded pump LD freely. The output power of each pump LD is controlled separately by the program that is set up by user. In the case optimum ASE source output features such as wide broadband (> 80 nm @ -10 dBm/nm) and stable output power (< 0.02 dB) is needed, it is made up so that the provided Default mode along with User mode can be chosen and set up. More stable application of ASE source is possible through the combination of monitoring of ASE output power, alarm status and pump LD status with real-time optimal feedback. The embedded FPGA processor makes high speed control possible and enables monitoring and feedback routine operated stably.

Light Distribution Photometer Goniophotometer
LCG-1600
-
Shenzhen Chuangxin Instruments Co., Ltd.
LCG-1600 Goniophotometeric System carries out measuring methods of fixed location and rotating luminaires. The measured luminaire is installed on the two-dimension rotating table, using “+” laser to make the luminaire lighting center superposed with the rotating center of rotating table. The mechanical equipment allows turning the tested luminaires around a vertical axis and a horizontal axis. When tested luminaires turn around horizontal axis, the detector which is at the same level with rotating table will measure the intensity of each direction at this surface. When rotating with vertical axis, the detector will measure the intensity at the vertical surface. The vertical and horizontal axis can be rotated continuously at ±180° or 0~360°. According to the measurement requirements, the system can be operated in C-γ coordinates. When getting intensity distribution data, computer will calculate other photometric parameters automatically.

Solar Simulator Continuous Light
-
This type of solar simulator uses Xenon high pressure arc lamps as light source. These lamps have a colour temperature near 5800 K, so it is feasible to filter the light output to an excellent AM 1.5 spectrum. If a tuneability of the spectrum is required, these lamps can be combined with tungsten lamps to achieve multi-source solar simulators. These can be used to measure tandem/triple/multijunction solar cells. They also allow detailed analysis of all types of solar cells using a spectral metric (see : Publication List).

Evaporative Light Scattering Detector
ELSD-LTII
-
The ELSD-LTII utilizes a high-efficiency LED and enhanced digital signal treatment to minimize noise and deliver optimum sensitivity for trace analysis. An innovative cell design also reduces band broadening and allows sensitivity levels below 200 picograms. The high-performance optical detection system can also be used for combinatorial chemistry and high-throughput screening applications. The new Low Temperature Evaporative Light Scattering Detector (ELSD-LTII) is an easy-to-operate, universal detector that identifies analytes with uniform sensitivity regardless of their spectroscopic properties. It is not a spectroscopic detector. Instead, it removes the mobile phase through evaporation and then makes a light scattering measurement of the dried analyte particles.
