Envi HSL-50 Slit Lamp
Envi's five-magnification tower slit lamp, sitting between the two-magnification HSL-20 and the premium ZSL-50 in the Envi slit lamp line.
Overview
The HSL-50 is the step up from the HSL-20 in Envi's slit lamp range. Where the HSL-20 gives two magnifications on a drum for routine anterior segment work, the HSL-50 broadens the magnification range for detailed examination while keeping the same tower-style build and LED illumination that the Envi lamps are known for. It is the middle option in a three-lamp line: HSL-20 for a straightforward exam lane, HSL-50 for a practice that wants more range without moving to the premium tier, and ZSL-50 at the top. Current published specifications come with your quote.

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.
- Run the magnification range against the cases you actually see
- Compare it side by side with the HSL-20 and ZSL-50 before deciding
- Ask for the current HSL-50 specification sheet
- Check the fit against your chosen instrument stand
