Two mirror bispectral device, corresponding system
The device has a system for double bending a band of wavelengths, and a dichroic semi-reflective blade (21) adapted to transmit another band (lambda 1) of wavelengths toward a bispectral lens (3) through another dichroic semi-reflective blade (22) and to reflect the former band of wavelengths toward...

Zusammenfassung: | The device has a system for double bending a band of wavelengths, and a dichroic semi-reflective blade (21) adapted to transmit another band (lambda 1) of wavelengths toward a bispectral lens (3) through another dichroic semi-reflective blade (22) and to reflect the former band of wavelengths toward the system. The latter semi-reflective blade is adapted to receive the latter band of wavelengths from the system and to reflect the latter band of wavelengths toward the lens, where the two bands of wavelengths are distinct from each other. |
