PT-1313G Multichannel Analog Phase Card
This multiaxis measurement-card series is a core component of dual-frequency laser interferometers, supporting precision phase measurement and counting on 1-5 axes. Fully digital construction provides strong interference resistance, environmental compensation, real-time feedback and direct fiber connection for precision displacement control. PT-1313G multichannel analog phase card: Compares reference and measurement signals in heterodyne laser interferometers to measure phase difference and perform integer counting, combining high accuracy with wide range. It measures input frequency with an automatically sampled frequency-counter function. Fully digital circuits measure dual-frequency interference and other phase signals on 1-4 axes simultaneously. Up to 4 signals are processed with integrity checks. High-rate acquisition and power through USB 2.0, compatible with USB 1.1, eliminate an external supply. Software upgrades are supported.

XNY-T6 Rotating Sensor Probe (Six Probes)
Metrology Accessories
Cdxnyzk
The rotating sensor head is used in demanding coating processes involving very thick films and multiple materials. Advantages: 1. Six crystals are placed in a thermally shielded, water-cooled tray to maintain excellent performance at ambient temperatures up to 300°C. 2. Pneumatic indexing of six crystal positions uses purely mechanical positioning with good repeatability and no cumulative error, with an in-position detection switch signal. 3. Easy installation, with main-body size Φ72 and customizable vacuum interface and insertion length. 4. Imported integrated MICRODOT TO BNC connector. 5. Replacing six crystals at once improves productivity and supports deposition of thicker films. 6. Rugged, durable construction with a complete 304 steel cylindrical housing.

Medical disposable‑device manufacturers have long demanded high‑performance interconnect accessories for single‑use equipment. The newly‑launched REDEL‑P disposable‑connector family addresses this requirement and delivers premium‑grade electrical connections for varied one‑time‑use medical instruments.
A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
BEIJING JIEPU TREND supplies YAG+Er:YAG+YAG bonded composite slab laser crystals for high‑power solid‑state laser systems. The monolithic slab consists of two undoped YAG end‑cap layers and a central Er‑doped YAG gain segment. The overall dimension is 9 mm×9 mm×9 mm.
Driven by the rapid upgrading of industrial automation, high-precision displacement sensing technology has become a core foundation of intelligent manufacturing.
