Leading since 1933

Model 320 - the slit lamp that started the legacy

Developed in close collaboration with Dr. Hans Goldmann, the first Haag-Streit slit lamp was introduced in 1933.

In 1937, its successor, the model 360 was presented, featuring a new single lever to make one-handed operation possible. The cornerstone was laid for a mutually fruitful collaboration with Professor Goldmann.
