Drawing Eyepiece for Drawing with kthe Microscope inclined.

No, s.

164. Drawing Eyepiece, similar to the preceding eyepiece but with a slightly modified prism, so thac when the microscope is inclined at 45° the image of the object may be seen on a drawing surface placed immediately behind the stand at the distance of normal vision. When the drawing surface is in its proper horizontal position relatively to the eye the image will be seen clearly and without distortion. The light may be moderated by means of two neutral tint glasses fitted in hinged mounts.

The advantageous position of the drawing surface and the convenience of drawing while the microscope is in an inclined position have brought this little instrument rapidly into favour...........................1. 5,

This Drawing Eyepiece is generally supplied in the form of an adaption of the ordinary Eyepiece No. II, but any other Huyghe-nian Eyepiece, with the exception of No. V, may be supplied as a drawing eyepiece of this type.
