The Heliopan Bay 70 RG 610 Infrared Filter is designed to help capture images of how a subject reflects or transmits infrared light.

Infrared light waves occupy the space in the electromagnetic spectrum behind visible light due to their longer wavelengths. Many surfaces and materials react to, or emit infrared light waves differently than visible light waves, which provide the potential for photographs of subjects or subject properties that are otherwise invisible to the human eye. Such images require an infrared-sensitive medium such as infrared film or a digital photographic sensor which may be more effective when used without the infrared-blocking filters that are frequently built over them.

Conventional light sources such as the sun, photographic strobes, or incandescent lighting may be used to provide infrared illumination. However, because infrared films or digital photographic sensors can be more sensitive to the relatively higher energy and shorter-wavelength visible light those sources also emit, the effects of infrared light can be otherwise obscured. The Heliopan Bay 70 RG 610 Infrared Filter makes it possible to capture images of how subjects are illuminated by infrared light by blocking near-infrared, visible, and ultraviolet light waves while allowing 90% of infrared light waves 610nm or greater into the lens it is mounted onto.

This filter is constructed from Schott glass for increased optical clarity and features a brass filter ring for durability and jamming prevention.

Q: 1. how do u check raid in this for bad sectors? i usually run apple disk utility and secure erase 2x on individ drives but what about RAIDS? i no see option for that on apple DUtility.

A: Apple Disk Utility should not be used with the OWC ThunderBay 4 4-Bay Thunderbolt 3 RAID Enclosure. You would need to use the free SoftRaid software to manage and maintain the unit.

Q: 2. Is it possible to JBOD with the Thunder Bay 4?

A: Yes. That's all i do with it. You can buy without the soft raid i think.

Q: 3. Hi, what is the difference between this OWC Thunderbay 4 enclosure and this other one that you have on your website (https://www.bhphotovideo.com/c/product/1635299-REG/owc_owctb3ivkit000_thunderbay_4_0tb_4_drive.html/overview) ?

A: BH #OWTB3SRKT0GB comes with the SoftRAID controller software included, while BH #OWCTB3IVKIT0 does not. Apart from this difference they are the same item.

Q: 4. Is there a way to connect a mac without a Thunderbolt port to this?

Q: 5. Does anyone have experience with the software RAID working with Mac OS Sierra? Thanks.

A: I can confirmed that we have updated our Mac Pro to Sierra and we haven't notice any problems. Perfect for collaborative work in FCPX

Q: 6. what is the warranty for this device (box AND drives)?

A: This product has a Limited 3-Year Warranty.

Q: 7. Does this require Synology HDD's?? Or can I use a 3rd party like Iron Wolf?

A: You can fill this Synology DiskStation DS1823xs+ 8-Bay NAS Enclosure with Synology's drives, or other 3.5mm drives such as the Seagate IronWolf Pro, or WD Red Pro drives.

Q: 8. Dose it come with a thunderbolt cable and if so what length?

A: Yes, a 1 meter cable is included.

Q: 9. Has anyone had any trouble with non-Synology memory modules, support or warranty service? Synology branded memory is overpriced.

A: Not using items that have been tested by Synology can affect your warranty coverage of the Synology DiskStation DS224+ 2-Bay NAS Enclosure BH #SYDS224PLUS.

Q: 10. Does the SoftRAID software run on an iMac?
