Substage Condensers

The function of the Substage Condenser is to direct a light beam of the desired numerical aperture and field size onto the specimen. There are several types of Condensers as follows:

The 1.25 N.A. Abbe Condenser with Iris Diaphragm, Cat. No. 31-55-12 (Fig. 6-1), is primarily for use with the Mirror, Cat. No. 31-50-66 or 31-50-67, and with the Optilume, Cat. No. 31-32-12, or Professional Optilume, Cat. 31-32-13.

The 1.25 N.A. Aplanatic Condenser with Iris Diaphragm, Cat. No. 31-55-13 (Fig. 6-1), is primarily for use with High Intensity . Base Illuminator, Cat. No. 31-32-14.

The 1.25 N.A. Flip-Out Condenser and Iris Diaphragm, Cat. No. 31-55-15 (Fig. 6-1), is required when using the 2.5X Objective in order to fill the field and aperture.

The 1.25 N.A. Abbe Condenser in a Spiral Focus Mount, Cat. No. 31-55-11, is for use with the Plain Stage for Spiral Focus Condenser, Cat. No. 31-60-11.

The Paraboloid and Cardioid Dark Field Condensers are discussed under Section 14, Dark Field Microscopy.

Turret Phase Condensers and Long Working Distance Phase Condensers are discussed in Section 12, Phase Contrast Microscopy.

A Flip-In Lens Attachment, Cat. No. 31-55-14 (Fig. 6-1) mounts on the 31-55-11, -12, -13 Condensers to permit filling the field of a 4X Objective.

An accessory slot in the bottom of these Condensers permits the insertion of a Blue Filter (not supplied with Condenser), Cat. No. 31-58-07-021.
