        LASICO Series 1600 Filar Eyepieces
(Measuring Oculars)

 

THE ECONOMICAL SOLUTION FOR MEASUREMENTS
OF SMALL OBJECTS UNDER A MICROSCOPE

 

 

Usable with virtually any optical microscope, Lasico Filar Eyepieces represent an economical solution to measuring problems faced by many manufacturing companies for gap and line width measurements, quantitative analysis in medical and biological research and general quality control applications. Lasico Filar Eyepieces are also employed as backup devices for large automatic line-width measuring systems.
If compared with mechanical measuring oculars, series 1602/1603 instruments provide a significantly improved measuring resolution, a considerably higher operating speed and much enhanced operator convenience. The typical readout and calculation errors of mechanical filar eyepieces are completely eliminated.

 

 

Lasico Digital Filar Eyepieces can convert any
optical microscope into a precision measuring tool.

 

 

 

Lasico Filar Eyepieces are available
for optical microscopes with 23.14 mm tube diameter (series 1602) and
for microscopes with 30mm tube diameter (series 1603).
If the large field of view provided by 30mm dia. oculars is not important, 1602 models can be equipped with a sleeve (# 1605-1) to fit 30 mm dia. tubes. Electronic Filar Eyepieces need to be operated in conjunction with a processor. Several processor models are available.
All can be interfaced with computers either via an optional interface for Mod. SM2, M, XM or via built-in interface in Mod. M2 and XM2.

 

 

The optics used is manufactured by major Optical Instrument Companies .

Filar Eyepiece Specifications:

Transducer: 2000 pulse/rev Incremental Shaft Encoder

The economical solution for the occasional user!

Results need to be obtained via a micrometer readout and are unscaled. The measuring resolution is lower than that of the electronic systems by a factor of 30.
