635nm 5mW Red Line Laser Diode Module for CT Scan Positioning

The 635nm 5mW Red Line Laser Diode Module—a medical-grade auxiliary optical component exclusively optimized for CT scan body positioning. Tailored to the strict requirements of CT room environments, medical device compatibility, and high-precision positional calibration, this module delivers a distortion-free, high-visibility red laser line for accurate patient body positioning in CT scanning (diagnostic CT/ radiotherapy planning CT). It features medical-grade safety compliance, anti-strong electromagnetic interference (EMI), ultra-stable low-power output, and compact, easy-integration design, ensuring precise patient positioning (reducing scan rework rate) and no interference with CT imaging systems—an essential core component for modern medical CT equipment.

Core Advantages for CT Scan High-Precision Positioning

1. 635nm Red Light: CT Room Optimized, No Imaging Interference + High Visibility

• 635nm (±5nm tolerance) low-power red light is the optimal wavelength for CT scan positioning: it has high naked-eye visibility under CT room dim lighting (no glare for medical staff/patients) and no electromagnetic/optical interference with CT X-ray imaging systems, avoiding image artifacts or signal distortion caused by laser light—ensuring the integrity of CT scan data.

• 5mW Class 2 low-power CW output meets the light intensity requirement for CT positioning (effective visible range 0.1–5m), with a clear laser line that can be stably projected on human skin, positioning cushions, and CT bed panels without overexposure or fading, enabling medical staff to complete rapid and accurate body marking.

• Neutral red light spectrum with narrow spectral linewidthdoes not react with CT room radiation shielding materials (lead plate/lead glass) or contrast agents, ensuring long-term stable projection without spectral drift-induced light intensity changes.

2. Medical-Grade High-Precision Straight Line: Zero Distortion for Accurate Positioning

• Ultra-high linearity performance: line straightness ≤±0.01mm/m, line width ≤1mm@1m (CT scan standard working distance) —the laser line has no bending, skewing, or middle thickening/edge fading, ensuring sub-millimeter level positioning accuracy for patient head, chest, abdomen, spine, and limb CT scanning.

• Fixed focus for CT positioning (0.1–5m optimal focus range): no need for manual focus adjustment, avoiding positioning errors caused by accidental focus shifts; the laser line is projected parallel to the CT bed/scan axis, perfectly matching the CT equipment’s scanning coordinate system and reducing scan deviation caused by incorrect patient posture.

• Anti-reflective optical window coating: eliminates secondary reflection of the laser line on CT bed plastic panels and metal brackets, avoiding ghost lines and double images that interfere with positioning judgment, and ensuring a single, clear laser reference line for medical staff.
