Envi HSL-20 Slit Lamp

Two-magnification tower slit lamp with 10x and 16x drum selection, the standard lamp in Envi's Essentials exam lane package.

Overview

The HSL-20 covers routine anterior segment examination with a convergent binocular microscope and two drum-selected magnifications. Vertical slit tilt to 20 degrees, continuously adjustable slit length, and generous base travel handle the everyday exam, and its place in the Envi Essentials Package makes it the default lamp in Envi lane buildouts.

What to ask on a demo

A demo is worth more when you arrive with your own cases and a list of questions. Here is what we would raise.

  • Compare 10x and 16x against the magnifications you actually use
  • See it mounted on the Switch or S2-S stand you are considering
  • Ask about the ZSL-50 if you want five magnifications
