Brunel Bright Field Transmission and Incident Fluorescence Inverted Microscope, finished to a high standard. The large stage will accept most types of laboratory apparatus, and the condenser assembly can be removed from the optical path for particularly tall objects. The microscope is equipped with long working distance plan objectives and plan phase contrast objectives. Offering a magnification range of x50 to x400.

Objectives

Plan long working: x 4, x10 and x25, - infinity tube length

Plan phase contrast: x10, and x40 - infinity tube length

Eyepieces

x10 widefield

Condenser

The long working distance condenser with a Zernicke phase contrast system has a working distance of 50mm. The potential specimen vessels for this type of microscope is very varied and the mechanical stage arrangement has been designed as an attachment that can be removed in order to accommodate unusual sized specimen equipment. The microscope has low position coaxial coarse and fine focus controls with inbuilt tension adjustment and variable safety stop. The fine focus control is graduated in 2 micron units as an indicator of depth. The microscope has a trinocular head and camera port for the attachment of CCTV and still image cameras.

Illumination systems

Transmitted bright field lighting with a 6v 30 watt tungsten halogen lamp. Reflected light, mercury vapour lamp output 100 watt DC power supply.

Fluorescent lighting system

The microscope provides four excitation filter systems. The barrier filters are long pass allowing transmission from the wavelengths shown in the table.

UV (ultraviolet) 330 - 400mm

V (violet) 395 - 415mm

B (blue) 420 - 485mm

G (green) 460 - 550mm
