3M 1880 Plus Overhead Projector

The 3M 1880 Plus Overhead Projector is engineered for durability with a chemically hardened, break-resistant stage glass. The durable stage glass can result in less maintenance, interruptions and repair expenses. The 3M 1880 Plus comes with an articulating closed-doublet lens for especially crisp screen images that make a lasting impression. There's a color-tuning dial for edge-to-edge brightness, and high-to-low intensity switch that adjusts from 2,700 to 3,000 lumens.
