Optical Zoom Lens for Microscope Cameras with 2.5X Objective
COMPLETELY TRANSFORM YOUR DRY BLOOD IMAGING
From the standard setup (Layer 5, 4X objective, no optical zoom lens):
To the new setup (Layer 5, 2.5X objective + optical zoom lens):
Change how you view and capture dry blood
One of the most important features of the NGS-2020 series of microscopes is the additional magnification in the trinocular tube, which produces 40X higher magnification on the viewing screen than through the eye pieces. This additional on-screen magnification is ideal in a live blood analysis microscope as it allows the user to achieve a higher level of magnification on the screen with a normal dry 40X objective (1600X) than what is achieved with a 100X oil objective (1000X) in other standard systems. This also enables the user to achieve a total magnification of 4000X with the 100X oil objective, ideal for advanced darkfield analysis.
The main trade-off with this configuration is that the additional on-screen magnification produces too high a level of magnification for dry blood imaging. The user is not able to see the same large field of view on the screen as what can be seen through the eye pieces. This can now be overcome with the optical zoom lens and 2.5X objective.
Optical Zoom Lens
- Attached between the microscope camera and the trinocular photo tube.
- Adjustable zoom allows the user to increase and decrease the magnification to the camera.
- Maximum zoom level ensures that the on-screen magnification of live
- blood remains unaffected.
- Minimum zoom level allows the user to fit a significantly larger portion of the dry blood sample on the screen.
- The standard 4X objective is replaced with a 2.5X objective, further reducing the magnification of dry blood samples.

Due to the large size of layers 1 and 2 in dry blood analysis, it won’t be possible to fit these layers entirely into the viewing screen. However, a much larger portion of these layers will be visible with the optical zoom lens and 2.5X objective, and in most cases layers, 4-8 will fit entirely into the screen. The adjustable zoom allows the user to increase the magnification in live blood analysis, thereby maintaining the additional on-screen magnification of the NGS-2020 series microscopes.
