Lasers

This microscope is equipped with a 405nm diode, a 561nm DPSS, a 633 HeNe, and an Argon laser with lines at 458nm, 488nm and 514nm.  It also has a Ti:Sapphire laser tuneable between the wavelengths of 720-1064nm, and the OPO is tuneable between 1050-1300nm.

1FSet49 wfZeiss Filter Set 49. Bandpass filter set for viewing DAPI and similar blue fluorophores down the eyepieces.
2FSet38 wfZeiss Filter Set 38. Bandpass filter set for viewing Alexa 488, eGFP and similar green fluorophores down the eyepieces.
3FSet43 wfZeiss Filter Set 43. Bandpass filter set for viewing TRITC, DsRed and similar orange fluorophores down the eyepieces.
4BS-MP 355/690+(R)Only for use with multiphoton. Reflects laser light >690 nm, and transmits light <690 nm to the non-descanned detectors.
5BS-MP -760Only for use with multiphoton. Reflects laser light >760 nm, and transmits light <760 nm to the non-descanned detectors.
6RearFor confocal imaging. Sends all light to the scan head.
