<%w-.ummShadowless Illumination forthe AKW Wide Field Microscope
NEW wide field microscope lamp hasC'00L been designed for the complete illumi-nation of opaque objects upon the stage of a lowpower microscope. Even though the specimenbe deep and cup-like with many irregularities,this lamp, by means of its ellipsoidal reflectingsurfaces, throws light into every corner and re-cess, eliminating all shadows.
This new lamp makes an ideal illuminant for theB & L AKW Microscope which has met withsuch enthusiastic approval as a wide field instru-ment. Because of its extremely wide field theAKW is suitable for a wide variety of uses.
The image, being neither inverted nor reversed,the long working distance and the stereoscopic
effect are particularly advantageous in dissect-ing work.
By simply rotating the drum, three sets ofpaired objectives of different magnification canbe instantly swung into approximate focus.
The high eyepoint enables even the wearer ofglasses to use the AKW without loss in the sizeof the field.
Write for further information on theseinstruments.
