The head-on type, also called the end-on type, receives incident light through the end of the glass bulb. It has a transmission mode photocathode deposited directly on the inner surface of the light input window and provides better spatial uniformity than the side-on type which uses a reflection mode photocathode. The head-on type also features a choice of photosensitive areas ranging from a few dozen square millimeters to several hundred square centimeters.\u003c\/p\u003e","brand":"webspareparts","offers":[{"title":"Default Title","offer_id":48171707400347,"sku":"R669, R669","price":0.0,"currency_code":"MXN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0516\/9263\/4267\/files\/iim_logo_prod_2.png?v=1774417938","url":"https:\/\/webspareparts.com.mx\/products\/hamamatsu-r669-photomultiplier-tube","provider":"webspareparts","version":"1.0","type":"link"}
