Optical Parametric Oscillator (OPO)


High Energy VIS-NIR Benchtop System

 

   The Vibrant 355 tunable laser system utilizes patented optical parametric oscillator (OPO) technology to generate wavelengths over a broad range in the UV, VIS and NIR (410-2400 nm). Integration of system components into one compact unit increases ruggedness and prevents misalignment. Hermetically sealed modules protect sensitive optical materials from the environment. All tunable beams exit the system from the same location resulting in one beam path to the end-user's application. The motorized OPO module connects through USB for computer control. The system includes the Nd:YAG pump laser, harmonics, low-divergence OPO, control software, SDK, and Signal/Idler selection.

 

 


Supercontinuum Generation (SCG)


Laser Diodes (LD) & CW Lasers

 

   Supercontinuum laser sources provide a white light output with the brightness of a laser and the spectral width of a lamp, effectively replacing most of the lasers and other light sources used today for fluorescence imaging, inspection, OCT, FLIM, FRET and a range of other applications in the entire 480-2400nm wavelength range.

   Olympus GX51 : Newly improved inspection efficiency thanks to UIS infinity-corrected optics, which allow high-clarity observation with flat, bright, even images right to the edge of the visual field (F.N.22). For high-magnification observation requirements, magnification settings extend from 5x to 100x when using eyepiece WH10x series. Suitable for both brightfield and simple polarizing observations. The polarizer can be rotated through 90°, allowing optimum contrast control. It has single lever switchover for brightfield/darkfield observation and standard 6V 100W halogen lamp and reflected light illuminator with aperture stop. Optimum contrast is obtained according to objective magnification and observation method. Handy filter pockets are provided, as various types of f25 filters can be used besides the polarizer.

DLP and ALP packages

 

 

 

 

 

 

 

 

DLP (Digital Light Processor)

ALP (Accessory Light Modulator Package)

 

   The DLP Board is not only designed to support application development, but can also be used to support low volume prototype equipment. In addition to the USB computer port, DLP Board features a high-speed parallel port that can be mated directly to the developer application specific signal processing board via two high-density data connectors.

 

   The ALP parallel interface controller produced for high speed DMD operation supporting both, binary and grayscale display of XGA patterns of different type. When used with the DLP Board, ALP is a turnkey tool providing free, direct and fast access to any single DMD mirror. The accessory is characterized by its high flexibility for customized solutions. A user friendly application programming interface (API) eliminates the need for any hardware and logic design. The user-PC is connected via an USB controller. XGA pattern sequences are loaded into the on-board SDRAM and are then transferred via the Discovery High-Speed Port to the DMD by specially designed high speed FPGA logic. The ALP supports both binary pattern sequences transferred to the DMD and the display of time average grey level picture sequences.

 

 

 

Power line communication (PLC)

 

 

 

 

 

 

 

 

  Power line communication (PLC), also called Broadband over Power Lines (BPL) or Power Line Telecoms (PLT), is a wireline technology that is able to use the current electricity networks for data and voice transmission. The carrier can communicate voice and data by superimposing an analog signal over the standard 50 or 60 Hz alternating current (AC).

 

   Traditionally electrical utilities used low-speed power-line carrier circuits for control of substations, voice communication, and protection of high-voltage transmission lines. One example of this technology is SCADA. More recently, high-speed data transmission has been developed using the lower voltage transmission lines used for power distribution. A short-range form of power-line carrier is used for home automation and intercoms. The MAX2986 powerline transceiver utilizes state-of-the-art CMOS design techniques to deliver the highest level of performance and flexibility. This highly integrated design combines the Media Access Control layer (MAC) and the Physical Layer (PHY) in a single chip. The MAX2986 digital baseband and its companion device, the MAX2980 analog front-end (AFE), offer a complete high-speed powerline communication solution that is fully compatible with third party HomePlug 1.0 devices.

Fused Fiber Coupler Fabrication System


Glass Fiber Processor (Vytran)


Polishing Machine

 

   Fused fiber coupler fabrication system(I) is an intelligent manufacturing station  ideal for the production of optical wave multiplexers/splitters for the Wavelength Division Multiplexing(WDM) communication systems. Several advaced technologies, such as high precision machining, high accurate and real time microstep control, high speed optical measurement and automatic data acquisition, are used to construct an PDPL Fused Fiber Coupler manufacturing system. Twin tip torch is adopted as a heat source, capable of precise temperature control. It is possible to manufacture different types of fiber couplers by onlychanging the software setup parameters.

 

   Vytran GPX-3000 is a unique, multipurpose glass processing platform for creating splices, combiners, tapers, couplers, end-caps and other fiber processes with optical fibers from 125 microns to 1.8 mm in diameter. GPX-3000 systems are built around a unique filament ¡°furnace¡± assembly 'a stable, intense heat source that can be precisely controlled over a wide temperature range' to ensure optimum glass processing conditions. The systems are ideal for R&D and production applications that demand accuracy, versatility and repeatability such as fiber laser and medical device manufacturing.

 

   Polishing machine is used for fabrication of side-polished optical fiber. Using a unique polishing process, side-polishing optical fibers creates a substrate of definable length and depth with parallel surface to guide facilitating access to the evanescent field, with virtually zero loss. Guiding properties are modified by structure and refractive index of overlay structure. By dynamic modification of structure dimensions, refractive index or absorption, time varying manipulation of the propagation can be achieved. Applications in optical fiber components and fiber optic sensing.
