Rectangular Refraction Glass Block, 100 x 60 x 18mm Type_Apron Borosilicate crown glass prism with

Borosilicate crown glass prism with refractive index 1

sized for measuring direction and field strength on the lab bench

sized for the medium-pitch terminal screws on bench supplies

the wider focal distance favoring page-wide field of view over higher magnification

3 glass beakers each holds 1000mL with low-form design and spout for large-volume chemistry and laboratory applications

Rectangular Refraction Glass Block, 100 x 60 x 18mm Type_Apron Borosilicate crown glass prism withPairs 100 by 60mm with 18mm thickness on a glass rectangular refraction block, the larger working face giving longer beam paths for measurable lateral displacement studies.
