Product Overview

1. High-Precision Rhomboid Prisms

Engineered for critical beam alignment tasks, our Rhomboid Prisms deliver pure beam translation without angular deviation. Unlike wedge or right-angle prisms, they shift the optical axis horizontally or vertically while maintaining perfect parallelism (<0.1° deviation). This ensures zero vignetting and preserves beam characteristics—diameter, collimation, and intensity profile—making them ideal for compact microscopy systems, laser spectroscopy, and medical imaging where space and precision are paramount.

2. Rhomboid Prisms Product Features

Rhomboid prisms are primarily used to produce a lateral beam offset without changing the beam direction or image orientation. Their key product features include:

1). Lateral Beam Displacement: the optical axis is shifted in parallel without flipping the image 

2). High Angular Accuracy: output beam is parallel to input beam within 30 arc seconds, some products up to ±3 arc seconds 

3). Material Options: common optical glass such as N-BK7, K9, UV fused silica, and also germanium for infrared applications 

4). Surface Quality: typically 60/40 or better, surface flatness up to λ/10 

5). Optional Coating: Anti-reflective (AR) or reflective coatings are available to enhance transmission or extend the angular range 

6). Customizable Size and Angle: dimensions and angular tolerances can be customized to meet specific application requirements 

These features make rhomboid prisms suitable for use in laser systems, imaging equipment, metrology, and AR/VR devices.

3. Rhomboid Prisms Applications

Rhomboid prisms are vital in fields like laser technology, instrumentation and biotechnology due to their ability to shift optical beams without altering their alignment. Here's a concise breakdown of their key applications:

1). Laser Technology

Raman Spectroscopy: Shifts the laser beam to align precisely with the sample—critical since a 0.1 mm misalignment can reduce signal intensity by 50%.
Fluorescence Microscopy: Moves the excitation beam to prevent blocking the detector, avoiding sample repositioning and potential damage.

2). Instrumentation

Optical Benches: Fine-tunes beam paths (e.g., shifting a laser 5 mm to align with mirrors/lenses).
Detector Offset Compensation: Ensures beams hit the active area of misaligned detectors (e.g., IR cameras), preventing signal loss.

3). Biotechnology

Live-Cell Imaging: Shifts excitation beams instead of moving samples, preserving focus and viability during long-term imaging.
Flow Cytometry: Aligns laser beams with cell flow paths, enhancing detection efficiency.

Key Advantage: Rhomboid prisms enable non-disruptive beam steering, ensuring precision in sensitive systems where mechanical adjustments are impractical or risky.
