Precautions against UV light exposure
∙ When UV light irradiation is applied, the product characteristics may degrade. Such examples include degradation of the product’s UV
sensitivity and increase in dark current. This phenomenon varies depending on the irradiation level, irradiation intensity, usage time,
and ambient environment and also varies depending on the product model. Before employing the product, we recommend that you
check the tolerance under the ultraviolet light environment that the product will be used in.
∙ Exposure to UV light may cause the characteristics to degrade due to gas released from the resin bonding the product’s component
materials. As such, we recommend that you avoid applying UV light directly on the resin and apply it on only the inside of the
photosensitive area by using an aperture or the like.
