I should note that the IR filter should NOT be removed unless you replace it with another and seal it completely.
Getting rid of it makes these no longer sealed. LBO is hygroscopic. If you leave the head in this condition, you'll be wondering why it slowly looses output over months until it finally quits lasing at all.
