LED 태양열 시뮬레이터 PCBA 보드 모듈 200-1750NM
단파 적외선 (일반적으로 범위는 1000 nm ~ 2500 nm) 에 빠진다 “광학 창” 생물학적 조직의. 가시광선이나 근적외선에 비해 (근적외선) 빛, SWIR 제안:
더 깊은 조직 침투 (산란 감소로 인해).
고대비 이미징 (due to specific absorption bands of water, lipids, and collagen).
Lower autofluorescence, resulting in a much higher signal-to-noise ratio.
그만큼 3535 패키지 (3.5 mm × 3.5 mm) is the industry standard for high-power density, offering excellent thermal management required for precise medical instruments.
🔬 Key Biomedical Applications & English Terminology
1. Optical Coherence Tomography (OCT) & Deep Tissue Imaging
SWIR LEDs serve as excellent, cost-effective light sources for non-invasive cross-sectional imaging.
English Terms: Deep tissue endoscopy, sub-surface vascular imaging, non-destructive optical biopsy.
Application Context: SWIR LEDs in the 1000–1300 nm range provide superior penetration depth through skin, bone, and teeth, enabling high-resolution imaging of subcutaneous blood vessels and early-stage dental caries.
2. Blood Glucose & Blood Lipid Monitoring (Non-Invasive)
Water has a relative absorption minimum around 1050–1300 nm, while glucose, lipids, and protein have distinct absorption peaks in the 1500–1700 nm range.
English Terms: Non-invasive blood glucose monitoring, lipid profiling, metabolic biomarker spectroscopy.
Application Context: By utilizing multi-wavelength 3535 SWIR LEDs, wearable medical devices can measure blood glucose levels transdermally without the need for painful needle pricks.
3. Blood Oxygenation & Hemoglobin Saturation (SpO2)
While standard pulse oximeters use Red and NIR light, SWIR wavelengths provide more accurate readings through thicker tissues or in conditions with poor peripheral perfusion.
English Terms: Advanced pulse oximetry, tissue oxymetry, cerebral oxygenation monitoring.
Application Context: High-power 3535 SWIR emitters allow for the measurement of tissue moisture and oxygen saturation levels deep within muscle tissues or the brain.
4. Fluorescence Endoscopy & Guided Surgery
In molecular imaging, SWIR-emitted light is used to excite specific contrast agents (like Indocyanine Green – ICG, or quantum dots) that fluoresce in the SWIR spectrum.
English Terms: Fluorescence-guided surgery (FGS), intraoperative tumor targeting, real-time perfusion assessment.
Application Context: During oncological surgeries, high-power SWIR illumination helps surgeons differentiate between healthy tissues and tumor margins with high precision.
5. Photobiomodulation (PBM) & Low-Level Light Therapy (LLLT)
Specific SWIR wavelengths stimulate cellular activity, accelerate wound healing, and reduce inflammation deep within muscles and joints.
English Terms: Deep tissue phototherapy, accelerated wound healing, targeted anti-inflammatory therapy.
