D-TOP optical system offers a new alternative to the optical experiment. By breaking the stereotype that says “optical system can not be moved due to the heavy and large”, we propose a highly stable optical system that is capable of carrying with a compact size.

φ20 Post Holder

It is a post stand of φ20mm that has been optimized for the low optical axis and compact for D-TOP.

D-TOP Base plate

Square type

It is a base plate to fix φ20mm post stand. By only a little loosing a clamping screw of slotted, it can be replaced holders without changing posit...

Rectangle type

It is a base plate to fix φ20mm post stand. It is used when thin elements such as a lens and a polarizer are placed close to the optical axis.

D-TOP Breadboard

It is a breadboard of B4 size for D-TOP. To remove wasted space regarding the placement of the existing holders, it adopted a matrix M3-16mm tap hole.

A high precision polished aspheric lens that can condense the collimated light into the range of diffraction limit.
For an illumination optical system and a simple experiment, it is not requested the low-scratch polishing for a laser. Reflectance and surfac...
Simple optical lab bench fitted with a table frame and rubber isolators placed between the bench and the table frame provides a basic level o...
