UL1000 Helium Leak Detector

Crystal Material: KD*P/BBO Operating Wavelength Range: 300-1100nm Clear Aperture: 8mm×8mm

The Electro-Optic Q-Switch Pockels Cell Module is a fast optical switching device based on the linear electro-optic (Pockels) effect in a nonlinear crystal. As shown in the drawing, the device is packaged in a compact rectangular metal housing with a large, clear optical aperture and a side-mounted high-voltage electrical connector, allowing convenient integration into a laser cavity. When a high-voltage pulse is applied, the crystal induces a controlled phase retardation of the transmitted polarized beam; in combination with intracavity polarizers, the module acts as an ultrafast intracavity loss switch. It is widely used for Q-switching of solid-state lasers, cavity dumping, pulse picking and regenerative amplifier injection/ejection. Key characteristics include low half-wave voltage, high extinction ratio, high optical transmission, nanosecond-level switching speed and high laser damage threshold, making it suitable for industrial, medical, scientific and LiDAR laser systems. Note: the source material contains only a product outline drawing without a written datasheet; the specifications listed are typical values for this product class and should be confirmed against the manufacturer's official datasheet.

Product Form: Roll Packaging Method: Black light-tight sealed bag Core Type: Cardboard core

The product shown is a roll of light-sensitive (photosensitive) recording film, supplied together with a black light-tight protective bag. The film is wound on a standard cardboard core in roll form, with a smooth, uniformly coated white/ivory surface. Because the emulsion is sensitive to light, the roll is packaged in an opaque black sealed bag to prevent exposure during storage and transportation. This type of film is designed for high-resolution laser imaging equipment such as laser photoplotters, imagesetters and phototypesetters, where a laser beam scans the film surface to record fine circuit patterns, text or graphics. After laser exposure, the film is developed to produce high-contrast, high-density images used as phototools or film positives in PCB fabrication and printing plate making.

Product Type: API software library (Dynamic Link Library, DLL) Supported File Format: WDF (waveform data file saved on Yokogawa measurement instruments) Supported Operating System: Windows 10 (32 bit or 64 bit) / Windows 11, English or Japanese version

The WDF File Access Library is a free API (Application Program Interface) provided as a DLL (Dynamic Link Library) that enables user applications on a Windows PC to acquire data from waveform data files (WDF) saved on Yokogawa measurement instruments. By linking the DLL, developers can build application software with functions such as getting measuring conditions and getting waveform data from recorded WDF files accessible over the PC storage environment. Dedicated DLLs are provided for waveform data saved with the DL850E series, DL350, DL950, SL2000, Yokogawa's Xviewer software, and the DLM3000, DLM3000HD, DLM5000 and DLM5000HD series. The library offers functions for getting measuring date/time, measuring trace (channel) information, measuring points, time data/measuring data, units of the time axis/measuring axis, and resolutions of the time axis/measuring axis. The software package includes the library body (DLL), DLL import library (.lib), the prototype declaration header file (WDFAPIPublic.h), and sample code for explicit DLL linking (WDFAPIWrapper.cpp).

Number of Adjustable Optical Mounts: 4 Number of Central Optical Units: 1 Rail Layout: Linear, dual-section (left/right of central unit)

Based on the provided image, the product is a linear optical rail (optical bench) system consisting of a long rail base, four adjustable optical mounts with vertical posts arranged on both sides of the rail, and a central enclosed optical unit with a multi-slot housing. The rail structure allows optical components such as lenses, mirrors or filters to be positioned precisely along a common optical axis. Note: the source image is severely degraded (high-threshold silhouette) and no text, brand or detailed specifications are legible; the extraction is therefore based on the visible mechanical structure of the product.

System Architecture: Floor-standing standardized instrument rack with integrated multi-layer modules Control Computer: Top-mounted desktop workstation with monitor and keyboard Upper Measurement Module: Analysis/measurement instrument with integrated display and front-panel controls

The product shown is a floor-standing, rack-mounted optoelectronic test and measurement platform. The system integrates multiple instruments into a single standardized cabinet: an upper measurement/analysis module with an integrated display, a middle layer containing benchtop instruments (a display/readout unit and a source or control unit), and a high-power lower module with a front-panel ventilation grille, which indicates forced-air cooling for driving or testing high-power devices. A dedicated computer workstation (monitor and keyboard) is mounted on top of the cabinet for system control, data acquisition and analysis. The whole rack is supported by leveling feet for stable laboratory or production-floor installation. Please note: the provided image contains no legible brand name, model number or numerical technical data; the description and parameters below are therefore based on the visible system configuration, and detailed electrical/optical specifications should be confirmed with the manufacturer's official datasheet.
