Ingenuity & Integrity: The Hamar Laser Story

Our company was born quietly, in a small suburban town.

As an enterprising and extremely talented young engineer employed by Perkin-Elmer, Martin Hamar helped design the world’s first laser alignment system. In 1967, intent on designing the most accurate laser alignment systems possible and marketing them with integrity, Hamar raised a modest amount of capital with the help of friends and founded the company that bears his name. Nurtured with Hamar’s determination and ingenuity, the inspired enterprise took root and grew.

Hamar Laser’s more than 53 years of experience goes into every Stealth Series shaft alignment system.

Fast-forward to the present: Today, Danbury, Connecticut-based Hamar Laser Instruments manufactures laser alignment systems that address virtually any alignment challenge, from complex multi-axis, machine tool geometry applications to simple shaft alignment applications, and serves a large and highly diversified global customer base. Martin Hamar is chairman of the board, and the holder of 26 U.S. and foreign patents. His son, Rod Hamar, as president, is leading the company into the future.

So how did Hamar Laser, born a geometry company, get into shaft alignment?

In the 1990s, Martin and his team saw that a competitor had come out with a shaft alignment system that looked “okay” but which they quickly realized could be much better. So they thought: Why not apply the company’s more than 25 years of geometry know-how to common shaft alignment problems? It would be good for the customer and Hamar Laser, and it would serve industry.

The S-640 4-Axis Shaft Alignment System with Couple1 Software was the progenitor of the Stealth Series.

Using insights gained from decades of geometry alignment experience, Hamar Laser designed and built the S-640, the first 4-axis shaft alignment system, the progenitor of the Stealth Series brand. The product line grew steadily and today includes a variety of shaft alignment tools including the brand’s flagship, the S-680 5-Axis Laser Alignment System.

The S-680 5-Axis Laser Alignment System is the flagship of the Stealth Series.

" The machine move stage is the most critical step in any alignment. Behind its great graphics, this is where we have seen the very high resolution and accuracy of the system pay real dividends, because the live move data on a Stealth system has proven to be dependable and accurate. I have been very impressed to be able to align a new motor to close tolerances on several occasions with only one alignment measurement, one combined vertical and horizontal live-move correction and a confirmation retest – job done!. Well, you may not always be able to align a machine that fast, but it shows two things: that the condition of the machinery being aligned makes a big difference, and that the Stealth lasers are truly up to the task!
