Near-Infrared Holographic Optical Tweezers System STH-NIR1
JCOPTIX NIR holographic tweezers comprise laser, illumination, imaging, and motion-control sections. A reflective phase-only spatial light modulator (SLM) modulates the NIR laser to trap particles and move them in XYZ. Transmitted Köhler illumination, a 100X Olympus apochromat, and USB3.0 monochrome camera show motion live. JCOPTIX NIR Holographic Optical Tweezers System software provides precise control, custom holograms, and trapping-force calculations; see its manual. Custom sources, imaging, and stages are available through support. Applicable model STH-NIR1; laser 976 nm, adjustable 0-1000 mW; particle diameters 50 nm-5 μm; 100X Olympus apochromat; USB3.0 monochrome camera; transmitted Köhler illumination. The SLM modulates 976 nm light for software-controlled three-axis motion of 50 nm-5 μm particles with live observation. A manual supports quick setup; engineers can assist online or on site if needed.

Mode-conversion patch cord
Research & Education
Oe-photonics
Mode field conversion: 9um to 6.5um Mode field conversion: 9um to 4.8um Mode field conversion: 9um to 4.0um
OE photonics' mode-field-conversion patch cord serves links between optical devices or between networks and devices requiring a mode-field change. After conversion and adjustment by equipment such as a power amplifier, the desired fiber mode field is obtained. It mainly converts between single-mode SM 9/125um and small mode fields of 6um, 4um, or 3um in patch-cord form. FC, SC, LC, and other connectors can be fitted to customer requirements.

For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
