Milestones

Founded Larsen Equipment Design in late ’81

1982 ~ Sold first polisher and was urged to attended CLMA Confereence

1983 ~ Gained customers Bausch & Lomb and Wesley-Jessen midyear which provided growth to market for independent CL manufacturers.

1984 ~ Analyzed lateral vs. radial polishing mechanics; led to development of the radial arm polisher.

1985 ~ Adopted “Reduce variation and variables in process”; led to Bridge Technology for multi-spindle polishers which eliminated 15 position variables and made the process immune to tool height variations-predictable results. Entered Precision Industrial Optics market with Six Spindle Radial Arm polisher. User results to 1 /10 wave form accuracy.

R&D collaboration with key progressive CL labs; helps CL industry.

1986 ~ Becomes involved in unique local design projects, result: stay focused on CL industry.

1993 ~ Free-form lathes (OTT, Variform) drive the CL industry to demand an effective polisher. LED develops the “Bladder Polisher” using a completely different approach, which results in a fundamental improvement to the industry for all existing BC designs and opens the possibility for exotic and large diameter designs. Makes “specialty lenses” part of regular production. This technology is eventually adopted by the spectacle industry.

Introduces the Static Blocker which gives control of the blocking process to the labs; reduces operator influence. Makes toric lens production easier. Makes labs more aware of the house-keeping aspects of CL manufacturing.

Blocking tooling and lathe collets become more closely scrutinized.

1998 ~ Autoblocker in limited release with relay operating system. Results in “hands off” operation with a reduction in CL rejects.

1999 ~ Awarded CE machine compliance, resulting in continued sales in Europe, but more importantly, improving the components and operator interface of LED products.

2000 ~ Introduction of Programmable Logic Controller (PLC) controlled Autoblocker with Pitch dispenser; further reduction in rejects and 90% reduction in pitch consumption.

2001 ~ Polymer Technology Corp retains Larsen Equipment to solve water soluble blocking compound problem on spin blockers; leads to development of “Wax Thickness Control” on the Autoblocker yielding constant blocking compound thickness regardless of variations in Center Thickness: less wax, less rejects.

2003 ~ Initiative to standardize blocking tooling results in Solid 12.7 precision ground tooling (now widely accepted).

2005 ~ With precision blockers and tooling available, process control becomes a real possibility. Transfer blocking is known with some labs practicing it (still many not to this day). Transfer blocking is the key to good optics and lathe turned edges.
