MICROSCOPY & LIFE SCIENCE

Microscopy

The use of our SWIR camera brings even more valuable information for microscopy processes thanks to the Infrared band, i.e: 900nm-1700nm. With SWIR microscopes, observe beyond the standard visible range microscopes.

Low dark current and longer exposure are required because of low signal application.

• Quantum Efficiency(QE): >85%peak
• Typical dark current: 2000e-/pixel/s @-15°C, 1200e-/pixel/s @-20°C
• Readout Noise (High gain mode): <40e-
• Cooling capacity : >50°C below ambient
• Cost-effective solution – Best price to performance ratio on the market

Biomedical Imaging

SWIR opens new opportunities for deep tissue imaging for In-vivo applications. Traditionally, for deep tissue imaging ionizing radiation is used (X-ray and Y-ray) but poses some risks to biological tissue.

Photoluminescence Imaging is preferred, using fluorescent Dye and excitation laser.
Traditionally Visible and NIR bands have been used:

• The visible band (400-650nm) is used only for superficial tissues (strong scattering and absorption).
• NIR band or NIR1 (850-900nm) has been used in the last 20 years.

SWIR or NIR2 (1300-1400nm) has the following advantages:

1. Stronger transmission than the NIR band
2. Lower scattering
3. Commercially available and FDA-approved dyes show strong emission in the NIR2 band.
