Schaumburg, Ill. Omron Electronics has developed a new series of mass-produced, injection-molded microlens arrays (MLAs), which is said to set a new industry standard for cost-effective parallel lenses for both multi-mode fiber (MMF) and single-mode fiber (SMF) configurations.
The new P1L MLAs are rated to operate in uncontrolled environments from -40°C to 85°C. Available in flat and right-angle configurations, standard flat sizes include 2.5 mm (W) x 6.4 mm (L) x 0.55 mm (H). Right-angle MLAs measure 2.6 mm (W) x 6.4mm (L) x 2.6 mm(H). Anti-reflective coating is available as an option.
These lens arrays feature easy alignments through the use of highly precise positioning holes based on MT guide-pin spacing. Flat MLAs are available in both collimator and focusing types. The right-angle version allows designers to bend light at an optical interface for increased design flexibility.
The company said injection-molded production results in easily customizable MLAs, including for various channel configurations (1 x 4, 2 x 12, etc.) and physical sizes. Insertion loss for a free space connection using these lenses has been measured as low as 0.5 dB when AR coating is applied and air gap is optimized.
The new MLAs are suitable for parallel optical linking in transceivers for a variety of optical interconnections, board-to-board and chip-to-chip interconnection and free-space optical connectivity.
The Omron P1L MLA is priced at $20 for the flat type and $30 for the right-angle type in low volumes. Delivery is from stock.
