PS-2151 thermocline sensor (temperature-difference sensor)
The PS-2151 thermocline sensor (temperature-difference sensor) lets students investigate the relationship between depth and temperature in bodies of water and is compatible with PASPORT interfaces. Students can now measure how temperature varies with depth in local streams and lakes. The thermocline sensor (temperature-difference sensor) measures depth automatically, eliminating manual reading of cable graduations and manual data entry. Its weighted housing stabilizes depth measurements in fast-flowing streams.

PS-2011 dual-channel Bluetooth interface Sensors Brolight
Interface Type: USB or Bluetooth 2.0 Interface: 4 (2 PASPORT interfaces, 1 voltage interface, 1 temperature interface)
The PS-2011 SPARKlink dual-channel Bluetooth interface lets teachers and students connect their devices by USB or Bluetooth to any of more than 70 PASPORT sensors in the PASCO range. Data are acquired with SPARKvue or PASCO Capstone. Teachers and students can use desktop or laptop computers running either program, or Bluetooth-enabled iOS or Android devices running the SPARKvue app. Note: SPARKlink Air connects to Google Chromebooks by USB but does not support Bluetooth connection to them.

Fully integrated 4-channel DVS optical module Sensors Oe-photonics
Sensing distance: typical:20 km Number of detection channels: 4 channels Modulation mode: External modulation
For multichannel, fully integrated distributed vibration sensing (DVS), the DVS-AOM-L series uses an ultra-narrow-linewidth laser with optimized optomechanical/electrical integration. Serial-port parameter configuration, high integration, environmental-interference resistance, compact size, and convenience are provided. Sharing a narrow-linewidth laser reduces multichannel costs, particularly for demanding sensing applications. Custom solutions and specifications are available to sensor-equipment manufacturers.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
