The optimum aperture angle that obtains a sufficient incident level for stable detection without making precise adjustment combines with high-quality optical axis accuracy with an optical axis inclination variation of ±2.5° or less between individual products to enable optical axis adjustment that is much faster than for previous products. All Fiber Units are inspected with a special jig before they are shipped to enable reliable installation without variations between individual products.

Finding the horizontal head (Fiber Unit) offset in the incident light range for a specific incident level of 1,500 during installation shows just how much wider the range is for the E32-LT35Z in comparison with a previous product (E32-T15ZR). In comparison with the difficult optical axis adjustment of previous products, the optical axis of the E32-LT35Z can be roughly adjusted in a short period of time to obtain the incident level required for stable detection.
